IMPORTANCE Short-term and long-term persistent postacute sequelae of COVID-19 (PASC) have not been systematically evaluated. The incidence and evolution of PASC are dependent on time from infection, organ systems and tissue affected, vaccination status, variant of the virus, and geographic region. OBJECTIVE To estimate organ system-specific frequency and evolution of PASC. EVIDENCE REVIEW PubMed (MEDLINE), Scopus, the World Health Organization Global Literature on Coronavirus Disease, and CoronaCentral databases were searched from December 2019 through March 2021. A total of 2100 studies were identified from databases and through cited references.Studies providing data on PASC in children and adults were included. The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines for abstracting data were followed and performed independently by 2 reviewers. Quality was assessed using the Newcastle-Ottawa Scale for cohort studies. The main outcome was frequency of PASC diagnosed by (1) laboratory investigation, (2) radiologic pathology, and (3) clinical signs and symptoms. PASC were classified by organ system, ie, neurologic; cardiovascular; respiratory; digestive; dermatologic; and ear, nose, and throat as well as mental health, constitutional symptoms, and functional mobility.FINDINGS From a total of 2100 studies identified, 57 studies with 250 351 survivors of COVID-19 met inclusion criteria. The mean (SD) age of survivors was 54.4 (8.9) years, 140 196 (56%) were male, and 197 777 (79%) were hospitalized during acute COVID-19. High-income countries contributed 45 studies (79%). The median (IQR) proportion of COVID-19 survivors experiencing at least 1 PASC was 54.0% (45.0%-69.0%; 13 studies) at 1 month (short-term), 55. 0% (34.8%-65.5%; 38 studies) at 2 to 5 months (intermediate-term), and 54.0% (31.0%-67.0%; 9 studies) at 6 or more months (long-term). Most prevalent pulmonary sequelae, neurologic disorders, mental health disorders, functional mobility impairments, and general and constitutional symptoms were chest imaging abnormality (median [IQR], 62.2% [45.8%-76.5%]), difficulty concentrating (median [IQR], 23.8% [20.4%-25.9%]), generalized anxiety disorder (median [IQR], 29.6% [14.0%-44.0%]), general functional impairments (median [IQR], 44.0% [23.4%-62.6%]), and fatigue or muscle weakness (median [IQR], 37.5% [25.4%-54.5%]), respectively. Other frequently reported symptoms included cardiac, dermatologic, digestive, and ear, nose, and throat disorders. CONCLUSIONS AND RELEVANCEIn this systematic review, more than half of COVID-19 survivors experienced PASC 6 months after recovery. The most common PASC involved functional mobility impairments, pulmonary abnormalities, and mental health disorders. These long-term PASC effects occur on a scale that could overwhelm existing health care capacity, particularly in low-and middleincome countries.
Background The temporal evolution of SARS-CoV-2 vaccine efficacy and effectiveness (VE) against infection, symptomatic, and severe COVID-19 is incompletely defined. The temporal evolution of VE could be dependent on age, vaccine types, variants of the virus, and geographic region. We aimed to conduct a systematic review and meta-analysis of the duration of VE against SARS-CoV-2 infection, symptomatic COVID-19 and severe COVID-19. Methods MEDLINE, Scopus, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, the World Health Organization Global Literature on Coronavirus Disease, and CoronaCentral databases were searched and studies were selected. Independent reviewers selected randomized controlled trials and cohort studies with the outcome of interest. Independent reviewers extracted data, and assessed the risk of bias. Meta-analysis was performed with the DerSimonian-Laird random-effects model with Hartung-Knapp-Sidik-Jonkman variance correction. The GRADE (Grading of Recommendations, Assessment, Development and Evaluation) approach was used to assess certainty (quality) of the evidence. Primary outcomes included VE as a function of time against SARS-CoV-2 infection, symptomatic and severe COVID-19. Results Eighteen studies were included representing nearly 7 million individuals. VE against all SARS-CoV-2 infections declined from 83% in the first month after completion of the original vaccination series to 22% at 5 months or longer. Similarly, VE against symptomatic COVID-19 declined from 94% in the first month after vaccination to 64% by the fourth month. VE against severe COVID-19 for all ages was high overall, with the level being 90% (95% CI, 87–92%) at five months or longer after being fully vaccinated. VE against severe COVID-19 was lower in individuals ≥ 65 years and those who received Ad26.COV2.S. Conclusions VE against SARS-CoV-2 infection and symptomatic COVID-19 waned over time but protection remained high against severe COVID-19. These data can be used to inform public health decisions around the need for booster vaccination.
The social risk factors for physical and relational peer victimization were examined within a mixed-gender sample of children with and without attention-deficit/hyperactivity disorder (ADHD). Participants were 124 children (ages 8-12 years; 48% boys), with 47% exhibiting sub-clinical or clinical elevations in ADHD symptoms. ADHD and oppositional defiant disorder (ODD) symptom counts were assessed based on parent- and teacher-reports; parents rated children's social problems and teachers rated children's use of physical and relational aggression and experiences of physical and relational victimization. A multiple mediator model was used to test whether there were indirect effects of ADHD or ODD symptoms on physical and relational victimization through social problems, physical aggression, or relational aggression. At the bivariate level, ADHD and ODD symptoms were both significantly associated with higher rates of physical and relational victimization. In the mediational model, there were significant indirect effects of ADHD symptoms on relational victimization via social problems, of ODD on relational victimization via relational aggression, and of ODD symptoms on physical victimization via physical aggression. Results suggest that there are distinct risk factors implicated in the physical and relational victimization of youth with ADHD and that the co-occurrence of ODD symptoms is important to assess. Clinical implications for addressing victimization in children with ADHD are discussed.
ObjectivesThe prevalence of cannabis use among pregnant women is increasing in the United States and places mothers and infants at risk of multiple adverse health outcomes. Given the uncertainty expressed by providers regarding how to approach cannabis use during pregnancy and the growing need for a systematic endeavor to curb use in this population, the aim of this study is to conduct a systematic review of interventions focused on reduction in cannabis use during pregnancy.MethodsWe conducted a systematic search of MEDLINE, PsycINFO, CINAHL, Web of Science, SCOPUS, and Cochrane Library to identify studies of interventions that target individuals that engaged in cannabis use during pregnancy. We included studies if they were randomized controlled trials, controlled studies, feasibility studies, pilot studies, as well as observational studies. The primary diagnostic outcome of interest is reduction in cannabis use.ResultsWe identified 9 studies for inclusion with sample sizes ranging from 15 to 658 pregnant people. Interventions involved brief counseling, cognitive behavioral therapy (CBT), motivational interviewing (MI), motivational enhancement therapy + cognitive behavioral therapy (MET-CBT), computer-delivered psychotherapy, and psychoeducation. The interventions that were effective primarily used MI, CBT, and/or MET. There was just 1 study that implemented a home intervention and one that explored computer-based psychotherapy.ConclusionsThe studies uncovered through this systematic review suggest that interventions involving CBT and/or MI demonstrate promise for decreasing cannabis use during pregnancy. There is a tremendous need for high-quality studies focused on this population, and the potential for remote and computer-based interventions should be explored more fully.
We sought to identify barriers to COVID-19 vaccine uptake among persons who are socially vulnerable in light of the natural cycle of innovation diffusion. Widespread adoption of a health innovation requires a cadre of opinion leaders to build on successes experienced by early adopters. One type of opinion leader in healthcare are health mavens: members of a community who maintain up-to-date health knowledge and share their knowledge others. We surveyed 139 persons who are socially vulnerable regarding their COVID-19 vaccination intention, and evaluated their responses based on psychological traits captured by two scales: innovativeness and health mavenism. Health mavenism was not strongly correlated with COVID-19 vaccine intention. Health mavens often relied on their own healthcare providers (n = 46) and health agency websites (n = 42) for vaccine information. Those who relied on their faith leaders (n = 4) reported a lower likelihood of getting vaccinated (31.5% vs. 76.0%, p < .05). The observed lack of support by health mavens represents a critical barrier to COVID-19 vaccine uptake; targeting campaigns to health mavens may increase COVID-19 vaccine uptake in socially vulnerable communities.
