Population-based prevalence surveys during the Covid-19 pandemic: A systematic review.

ABSTRACT: Population-based prevalence surveys of Covid-19 contribute to establish the burden of infection, the role of asymptomatic and mild infections in transmission, and allow more precise decisions about reopen policies. We performed a systematic review to evaluate qualitative aspects of these studies, assessing their reliability and compiling practices that can influence the methodological quality. We searched MEDLINE, EMBASE, bioRxiv and medRxiv, and included cross-sectional studies using molecular and/or serological tests to estimate the prevalence of Covid-19 in the general population. Survey quality was assessed using the Joanna Briggs Institute Critical Appraisal Checklist for Prevalence Studies. A correspondence analysis correlated methodological parameters of each study to identify patterns related to higher, intermediate and lower risks of bias. The available data described 37 surveys from 19 countries. The majority were from Europe and America, used antibody testing, and reached highly heterogeneous sample sizes and prevalence estimates. Minority communities were disproportionately affected by Covid-19. Important risk of bias was detected in four domains: sample size, data analysis with sufficient coverage, measurements in standard way and response rate. The correspondence analysis showed few consistent patterns for high risk of bias. Intermediate risk of bias was related to American and European studies, municipal and regional initiatives, blood samples and prevalence >1%. Low risk of bias was related to Asian studies, nationwide initiatives, reverse-transcriptase polymerase chain reaction tests and prevalence <1%. We identified methodological standards applied worldwide in Covid-19 prevalence surveys, which may assist researchers with the planning, execution and reporting of future population-based surveys.

Project description:Purpose of reviewThe COVID-19 pandemic changed people's lifestyles and such changed lifestyles included the potential of increasing addictive behaviors. The present systematic review and meta-analysis aimed to estimate the prevalence of different behavioral addictions (i.e., internet addiction, smartphone addiction, gaming addiction, social media addiction, food addiction, exercise addiction, gambling addiction, and shopping addiction) both overall and separately.Recent findingsFour databases (PubMed, Scopus, ISI Web of Knowledge, and ProQuest) were searched. Peer-reviewed papers published in English between December 2019 and July 2022 were reviewed and analyzed. Search terms were selected using PECO-S criteria: population (no limitation in participants' characteristics), exposure (COVID-19 pandemic), comparison (healthy populations), outcome (frequency or prevalence of behavioral addiction), and study design (observational study). A total of 94 studies with 237,657 participants from 40 different countries (mean age 25.02 years; 57.41% females). The overall prevalence of behavioral addiction irrespective of addiction type (after correcting for publication bias) was 11.1% (95% CI: 5.4 to 16.8%). The prevalence rates for each separate behavioral addiction (after correcting for publication bias) were 10.6% for internet addiction, 30.7% for smartphone addiction, 5.3% for gaming addiction, 15.1% for social media addiction, 21% for food addiction, 9.4% for sex addiction, 7% for exercise addiction, 7.2% for gambling addiction, and 7.2% for shopping addiction. In the lockdown periods, prevalence of food addiction, gaming addiction, and social media addiction was higher compared to non-lockdown periods. Smartphone and social media addiction was associated with methodological quality of studies (i.e., the higher the risk of boas, the higher the prevalence rate). Other associated factors of social media addiction were the percentage of female participants, mean age of participants, percentage of individuals using the internet in country, and developing status of country. The percentage of individuals in the population using the internet was associated with all the prevalence of behavioral addiction overall and the prevalence of sex addiction and gambling addiction. Gaming addiction prevalence was associated with data collection method (online vs. other methods) that is gaming addiction prevalence was much lower using online methods to collect the data.SummaryBehavioral addictions appeared to be potential health issues during the COVID-19 pandemic. Healthcare providers and government authorities should foster some campaigns that assist people in coping with stress during COVID-19 pandemics to prevent them from developing behavioral addictions during COVID-19 and subsequent pandemics.Supplementary informationThe online version contains supplementary material available at 10.1007/s40429-022-00435-6.

Project description:PurposeThe COVID-19 pandemic has affected orthopedic practices worldwide. Few studies focusing on epidemiology and management of fractures in COVID-19 patients have been published. We conducted a systematic review to evaluate the fracture types, presentation, treatment, complications, and early outcomes of fractures occurring amidst COVID-19 pandemic.MethodsA systematic review of the all published papers was conducted with a comprehensive search of PubMed, Google Scholar, Scopus, and Cochrane Library database using keywords 'COVID-19', 'Coronavirus', 'trauma∗'and 'fracture' from January-April 2020.ResultsThe searches yielded a total of ten studies with 112 Patients who were positive for COVID-19 associated with fractures was performed for six studies, reporting data separately for 44 patients with COVID 19 and an associated fracture. A diagnosis of COVID 19 was made on the basis of positive Computed Tomography scan in 39 patients and 30 patients had a positive Reverse Transcription-Polymerase Chain Reaction test. Overall, there were 29 proximal femoral fractures, 8 spine fractures, 7 fractures of the other bones. The fractures were treated surgically in 30 cases (68.18%) and the remaining 14 cases (31.82%) were managed conservatively. There were 16 patients (36.36%) who died, mostly due to respiratory failure with a median age of 82 years.ConclusionCOVID-19 has led to a significant reduction in a load of fracture patients globally, though the incidence of fragility fractures continues to be unaffected. There is a significantly higher risk of mortality in elderly patients with fractures and hence they should only be operated in a facility with a robust intensive care. Conservative treatment should be adopted as far as possible in non-obligatory fractures and in lesser equipped centers. Surgery in patients with proximal femur fragility fractures when judiciously selected did result in improvement in respiratory status. Reorganizing medical services is vital to deliver effective fracture care and also mitigate disease transmission.
