COVID-19 pandemic and suicidal behavior in adults: systematic review of observational studies

OBJECTIVE

To analyze the scientific evidence on the impact of the COVID-19 pandemic on suicidal behavior in adults.

METHOD

Systematic review, conducted from June to October 2022, in the following databases: MEDLINE/PubMed, Virtual Health Library, Excerpta Medica database, Cumulative Index to Nursing and Allied Health Literature, Latin American and Caribbean Health Sciences Literature, PsycINFO, Web of Science, Scopus, Science Direct and Google Scholar. The selection, data extraction and assessment of methodological quality were carried out using the Methodological Index for Non-randomized Studies tool. Considering that most of the studies evaluated had significant methodological differences, it was decided to carry out a qualitative synthesis of the data.

RESULTS

A total of 2112 articles were found, from which eight articles were selected that analyzed the impact of the COVID-19 pandemic on suicidal behavior in adults.

CONCLUSION

The COVID-19 pandemic has influenced the suicidal behavior in adults worldwide, especially when related to race, gender, age, religion, socioeconomic, family and legal issues, and pre-existing mental disorders, leading to a greater propensity for suicidal act.

Safety, Efficacy, and Immunogenicity of Therapeutic Vaccines for Patients with High-Grade Cervical Intraepithelial Neoplasia (CIN 2/3) Associated with Human Papillomavirus: A Systematic Review

Despite the knowledge that HPV is responsible for high-grade CIN and cervical cancer, little is known about the use of therapeutic vaccines as a treatment. We aimed to synthesize and critically evaluate the evidence from clinical trials on the safety, efficacy, and immunogenicity of therapeutic vaccines in the treatment of patients with high-grade CIN associated with HPV. A systematic review of clinical trials adhering to the PRISMA 2020 statement in MEDLINE/PubMed, Embase, CENTRAL Cochrane, Web of Science, Scopus, and LILACS was undertaken, with no data or language restrictions. Primary endpoints related to the safety, efficacy, and immunogenicity of these vaccines were assessed by reviewing the adverse/toxic effects associated with the therapeutic vaccine administration via histopathological regression of the lesion and/or regression of the lesion size and via viral clearance and through the immunological response of individuals who received treatment compared to those who did not or before and after receiving the vaccine, respectively. A total of 1184 studies were identified, and 16 met all the criteria. Overall, the therapeutic vaccines were heterogeneous regarding their formulation, dose, intervention protocol, and routes of administration, making a meta-analysis unfeasible. In most studies (n = 15), the vaccines were safe and well tolerated, with clinical efficacy regarding the lesions and histopathological regression or viral clearance. In addition, eleven studies showed favorable immunological responses against HPV, and seven studies showed a positive correlation between immunogenicity and the clinical response, indicating promising results that should be further investigated. In summary, therapeutic vaccines, although urgently needed to avoid progression of CIN 2/3 patients, still present sparse data, requiring greater investments in a well-designed phase III RCT.

Quality of life of transgender people under the lens of social determinants of health: a scoping review protocol

INTRODUCTION

There is an urgent need for knowledge about the transgender population to inform the development of clinical protocols and training of health professionals on the unique issues affecting this population. Discussing transgender quality of life (QoL) through the lens of social determinants of health (SDOHs) would enable gender-specific health interventions. Here, we aimed to review the evidence on the QoL of transgender people from an SDOH perspective.

Effect of omega-3 supplementation on the nutritional status of patients with pancreatic cancer: A protocol for systematic review of clinical trials

BACKGROUND

Globally, pancreatic cancer is the seventh most common cause of cancer-related death in both sexes, accounting for 466,003 deaths and 495,773 new cases in 2020. The purpose of this study was to synthesize and evaluate evidence on the effects of omega-3 supplementation on the nutritional status of patients with pancreatic cancer.

METHODS

This systematic review protocol will be guided by Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols. Five databases will be searched: MEDLINE/PubMed, CENTRAL Cochrane, EMBASE, Web of Science, and SCOPUS, with no restrictions on the publication date nor language. The internal validity and risk of bias of randomized controlled trials will be assessed using the revised Cochrane Risk-Of-Bias tool for randomized trials (RoB 2), whereas the risk of bias in non-randomized studies of interventions will be evaluated using the ROBINS-I. The heterogeneity among the studies will be assessed using the I2 statistic. Based on the results of this test, we will verify whether the meta-analysis would be feasible. If feasibility would be confirmed, a random-effect model analysis will be performed. For data analysis, the calculation of the pooled effect estimates will have a 95% confidence interval, while the alpha will be set to 0.05 using the R statistical software version 4.0.4. All methodological steps of this review will be performed independently by two reviewers and will be conducted and managed in the EPPI-Reviewer Software™.

RESULTS

This review may be of particular interest to researchers and clinicians, given the low survival and overall burden of patients with pancreatic cancer. Furthermore, the results of this systematic review may contribute to the development of new nutritional interventions in these patients.

CONCLUSION

To the best of our knowledge, this will be the first study to critically assess the scientific evidence and estimate the effect of omega-3 supplementation on the nutritional status of patients with pancreatic cancer. The review will perform a rigorous approach, adhering to the PRISMA Statement 2020 using a comprehensive and systematic search strategy in five databases and additional sources with no time period nor language restrictions.

Biomarkers of stress in caregivers of children with special health care needs: A protocol for systematic review

BACKGROUND

Children with Special Health Care Needs (CSHCN) require greater attention from family caregivers as they present temporary or permanent physical, developmental, behavioral, or emotional issues. This demand for care generates overload and stress among family caregivers. So far, there is no study that gathers the available literature regarding the use of biomarkers to assess stress among caregivers of CSHCN. Hence, we aimed to synthetize and to assess the scientific evidence on biomarkers associated with stress in caregivers of CSHCN.

METHODS

This systematic review and meta-analysis protocol was elaborated following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P). The search strategy will be undertaken through 7 electronic bibliographic databases: Embase, MEDLINE/PubMed, Cochrane Library, Web of Science, CINAHL, Scopus, and PsycINFO. In addition, secondary searches in other sources, such as Clinical trials.gov-NIH, The British Library, Pro Quest Dissertations Database, Google Scholar, and medRXiv will be also carried out. The reference section of the included studies will be hand searched for additional relevant studies. There will be no restriction regarding the publication dates or languages for this systematic review. Moreover, in an independently manner, 2 investigators will select studies, perform data extraction, as well as perform a critical appraisal of the risk of bias and overall quality of the selected studies, based on their designs. The heterogeneity among the studies will be assessed using the I2 statistic test. According to the results of this test, we will verify whether a meta-analysis is feasible. If feasibility is confirmed, a random-effect model analysis will be carried out. For data analysis, the calculation of the pooled effect estimates will consider a 95% CI and alpha will be set in 0.05 using the SPSS version 23.0.

RESULTS

This systematic review and meta-analysis will provide better insights regarding the biomarkers associated with stress in caregivers of CSHCN. Hence, consistent data and robust evidence will be provided to help practitioners and decision-makers in this area.

CONCLUSIONS

To the best of our knowledge this study, will be the first to synthetize and critically evaluate the scientific evidence on biomarkers associated with stress in caregivers of CSHCN.

Cost-effectiveness of home care services versus hospital care for pediatric patients worldwide: A protocol for systematic review and meta-analysis

BACKGROUND

Despite the expansion of home care services (HCS) in several countries, there is still a need to systematically investigate the available evidence on the cost-effectiveness of this type of service compared to hospital care in the world, particularly for the pediatric population. Hence, we aimed to systematically synthesize and critically evaluate the evidence on the cost-effectiveness of HCS versus in-hospital services worldwide.

METHODS

A systematic review and meta-analysis protocol guided by Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols. Ten databases will be searched: MEDLINE/PubMed, Cochrane Library, Excerpta Medica database, cummulative index to nursing and allied health literature (CINAHL), Web of Science, SCOPUS, Science Direct, PsycINFO, Latin American and Caribbean Health Sciences Literature and Chinese national knowledge infrastructure with no restrictions on publication date or languages. A checklist for assessing the quality of reporting of economic evaluation studies will be applied. To assess the methodological quality of evidence from observational research on comparative effectiveness, the Good Research for Comparative Effectiveness Checklist v5.0 will be used. The heterogeneity among the studies will be assessed using the I2 statistic test. According to the results of this test, we will verify whether a meta-analysis is feasible. If feasibility is confirmed, a random-effect model analysis will be carried out. For data analysis, the calculation of the pooled effect estimates will consider a 95% CI and alpha will be set in 0.05 using the R statistical software, v.4.0.4. In addition, we will rate the certainty of evidence based on Grading of Recommendations Assessment, Development and Evaluation. All methodological steps of this review will be performed independently and paired by 2 reviewers and conducted and managed in the EPPI-Reviewer Software™.

RESULTS

The results may have relevance for the basis of public health policies, regarding the forms of organization of HCS, especially in terms of complete economic evaluations through cost-effectiveness analysis in relation to hospital care.

CONCLUSION

To the best of our knowledge this will be the first systematic review and metanalysis to synthesize and critically evaluate the evidence on the cost-effectiveness of HCS versus in-hospital services worldwide. The review will adopt a rigorous approach, adhering to PRISMA Statement 2020, using a comprehensive and systematic search strategy in 10 databases, further the gray literature, pre-prints, with no time period or language restrictions.

Cancer symptom clusters in adult patients undergoing chemotherapy: A systematic review and meta-analysis protocol

Background

In oncology, the prevalence of symptoms is preferentially analyzed in isolation instead of being considered in clusters. However, clinical practice shows that symptoms rarely occur separately but rather form clusters that share common underlying mechanisms in terms of intensity and severity, creating a synergistic effect among them, which can even help predict the development of future symptoms.

Objective

To identify and gather evidence on the prevalence, composition, severity, and predictors of cancer symptom clusters in adult cancer patients undergoing chemotherapy.

Methods

This systematic review and meta-analysis protocol was developed in compliance with PRISMA-P. Observational and experimental study designs will be included. MEDLINE/PubMed, Cochrane Library, Embase, CINAHL, PsycINFO, Web of Science, Scopus, LILACS, clinical trials.gov-NIH, the British Library, Google Scholar, and preprints [medRXiv] will be searched with no restrictions on idioms, dates, or settings. Two investigators will independently select the studies, perform data extraction, and critically appraise the risk of bias of the included studies. Heterogeneity among the studies will be assessed using the I² statistic. If meta-analysis was feasible, a random-effect model analysis will be carried out. For data analysis, the pooled effect will be estimated considering 95% confidence interval and α = 5%. In addition, the certainty of evidence will be rated based on Cochrane methods in accordance with the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE).

Discussion

To the best of our knowledge, this systematic review and meta-analysis will be the first to identify and critically assess evidence regarding the prevalence, composition, severity, and predictors of cancer symptom clusters in adult cancer patients undergoing chemotherapy. We intend to provide health professionals with subsidies to reflect on a better understanding of symptom clusters in adult cancer patients, with the aim of contributing to the development of evidence-based therapeutic interventions and success in clinical practice.

Use of family history taking for hereditary neoplastic syndromes screening in primary health care: A systematic review protocol

Background

Although most neoplasms result from complex interactions between the individual’s genome and the environment, a percentage of cases is particularly due to inherited alterations that confer a greater predisposition to the development of tumors. Hereditary Neoplastic Syndromes have a high psychosocial and economic burden, in addition to being characterized by an increased risk for one or more types of cancer, onset of malignancy at a young age, high risk of secondary malignancies, and occurrence in successive generations of the family. Personal and family history, as well as pedigree, may be useful resources to estimate the risk for developing cancer, especially in Primary Health Care settings.

Objective

To identify and evaluate the evidence regarding the impact of using family history as a genomic technology for Hereditary Neoplastic Syndromes screening at Primary Health Care.

Methods

This systematic review protocol was elaborated in compliance with the Preferred Reporting Items for Systematic Review and Meta-analysis Protocols (PRISMA-P). We will include all observational as well as experimental study designs published up to end of July 2022, and studies covering the impact of family history on screening for Hereditary Neoplastic Syndromes in primary health care. Qualitative studies, as well as guidelines, reviews, and studies undertaken in hospitals, outpatient clinic, or medical environments will be excluded. Five databases will be searched, including MEDLINE/PubMed, Cochrane Library, EMBASE, Web of Science, and LILACS. Additional sources will also be retrieved, including Clinical trials.gov-NIH, The British Library, and Google Scholar. No restriction to language or date will be employed in the search strategy. Three investigators will select studies independently, perform data extraction, and conduct the critical appraisal of the risk of bias and overall quality of the selected studies according to their designs. Regarding data synthesis, the study characteristics will be summarized and presented in tables and results will be presented according to the study design. A qualitative synthesis of data will also be provided in this systematic review.

Discussion

To the best of our knowledge, this systematic review will be the first to identify and critically assess evidence regarding the impact of using family history as a genomic technology for Hereditary Neoplastic Syndromes screening in Primary Health Care settings worldwide. This study is expected to provide consistent evidence that will aid the primary care decision-makers regarding hereditary cancer screening, thus helping individuals and families at risk for cancer.

School reopening and risks accelerating the COVID-19 pandemic: A systematic review and meta-analysis protocol

BACKGROUND

One of the most recent concerns of this pandemic regards the role of schools reopening in disease transmission, as well as the impact of keeping schools closed. While school reopening seems critical for the education and mental health of children, adolescents, and adults, so far the literature has not systematically reached a consensus whether to recommend the return to schools in a way that would be safe for students and staff.

OBJECTIVE

To synthesize and critically evaluate the scientific evidence on the potential risk of accelerating the Coronavirus Disease 2019 (COVID-19) pandemic among children, adolescents, young adults, and adults with school reopening.

METHODS

This systematic review and meta-analysis protocol was elaborated following the PRISMA-P. We will include all observational study designs, which report on the potential risk of accelerating the COVID-2019 pandemic with school reopening. Electronic databases included were MEDLINE/PubMed, Cochrane Library, EMBASE, Web of Science, SCOPUS and CNKI. Additional sources will be also retrieved, including Clinical trials.gov-NIH, The British Library, Pro Quest Dissertations Database, Public Health Gray Literature Sources and Health Evidence, Google Scholar, and pre-prints [medRXiv]. No restriction to language or date will be used as search strategy. In an independently manner, two investigators will select studies, perform data extraction, as well as perform a critical appraisal of the risk of bias and overall quality of the selected observational studies, based on their designs. The heterogeneity among the studies will be assessed using the I2 statistic test. According to the results of this test, we will verify whether a meta-analysis is feasible. If feasibility is confirmed, a random-effect model analysis will be carried out. For data analysis, the calculation of the pooled effect estimates will consider a 95% CI and alpha will be set in 0.05 using the R statistical software, v.4.0.4. In addition, we will rate the certainty of evidence based on Cochrane methods and in accordance with the Grading of Recommendations Assessment, Development and Evaluation (GRADE).

EXPECTED RESULTS

This systematic review and meta-analysis will provide better insights into safety in the return to school in the context of the COVID-2019 pandemic, at a time when vaccination advances unevenly in several countries around the world. Hence, consistent data and robust evidence will be provided to help decision-makers and stakeholders in the current pandemic scenario.

Physiopathology and effectiveness of therapeutic vaccines against human papillomavirus

Human papillomavirus (HPV) is a well-known sexually transmitted disorder globally. Human papillomavirus (HPV) is the 3rd most common cancer that causes cervical carcinoma, and globally it accounts for 275,000 deaths every year. The load of HPV-associated abrasions can be lessened through vaccination. At present, three forms of prophylactic vaccines, Cervarix, Gadrasil, and Gardasil 9, are commercially accessible but all these prophylactic vaccines have not the ability to manage and control developed abrasions or infections. Therefore, a considerable amount of the population is not secured from HPV infectivity. Consequently, the development of therapeutic HPV vaccines is a crucial requirement of this era, for the treatment of persisting infections, and to stop the progression of HPV-associated cancers. Therapeutic vaccines are a developing trial approach. Because of the constitutive expression of E6 and E7 early genes in cancerous and pre-cancerous tissues, and their involvement in disturbance of the cell cycle, these are best targets for this therapeutic vaccine treatment. For the synthesis and development of therapeutic vaccines, various approaches have been examined comprising cell-based vaccines, peptide/protein-based vaccines, nucleic acid-based vaccines, and live-vector vaccines all proceeding towards clinical trials. This review emphasizes the development, progress, current status, and future perspective of several vaccines for the cure of HPV-related abrasions and cancers. This review also provides an insight to assess the effectiveness, safety, efficacy, and immunogenicity of therapeutic vaccines in the cure of patients infected with HPV-associated cervical cancer.

Suicidal behaviour in adults during the COVID-19 pandemic: protocol for systematic review of observational studies

INTRODUCTION

COVID-19 pandemic has an impact on mortality indicators worldwide. Mitigation and repression actions to reduce the morbidity and mortality associated with the disease are necessary. However, they are criticised in the economic, social and psychological spheres. This social isolation, increased unemployment, routine changes, news of health complications and deaths related to COVID-19 can cause psychological repercussions that will certainly intensify in the coming months, and suicidal behaviour presents itself as a fatal outcome. It is necessary to know factors associated with suicidal behaviour in adults during the pandemic. Although there are studies, there is no systematic review to assess these factors, specifically in adults. The objective is to critically synthesise the scientific evidence on the factors associated with suicidal behaviour in adults in the COVID-19 pandemic.

METHODS AND ANALYSES

A systematic review will be carried out, recommended by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol, in seven databases: Medical Literature Analysis and Retrieval System Online (MEDLINE), ISI of Knowledge, Excerpta Medica Database (EMBASE), SCOPUS, Latin American and Caribbean Health Sciences Literature (LILACS), Chinese National Knowledge Infrastructure (PsycINFO), Chinese National Knowledge Infrastructure (CNKI) and ScienceDirect. Preliminary search was carried out on 30 July 2020 and will be updated in March 2021. No restrictions on publication date, study location or languages will be considered in this review. The preliminary research strategies were carried out on 30 July 2020 and will be updated in February 2021. To measure the agreement between reviewers at each screening stage, Cohen's Kappa will be calculated. Primary outcome will be factors related to suicidal behaviour in adults during COVID-19 pandemic. Grouped standardised mean differences and 95% CIs will be calculated. The risk of bias in observational studies will be assessed using the Methodological Index for Non-Randomised Studies (MINORS). Statistical heterogeneity will be assessed with the I2 statistic.

ETHICS AND DISCLOSURE

Ethical approval is not required, as primary data will not be collected. The findings will be disseminated through peer-reviewed publications.

Effectiveness of complementary therapies for the management of symptom clusters in palliative care in pediatric oncology: a systematic review

OBJECTIVE

To evaluate the effectiveness of complementary therapies in the management of symptom clusters in children and adolescents with cancer undergoing palliative care.

METHOD

Systematic review guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses, resorting to the databases MEDLINE, Web of Science, Central Cochrane, and PsycINFO. The identification, selection, inclusion, extraction, and methodological assessment were conducted by two independent reviewers.

RESULTS

Five quasi-experiments met the eligibility criteria. The heterogeneous characteristics of the studies made meta-analysis impossible. Two studies used therapeutic massage, one used Reiki, one used boswellic acid, and one used Cannabis sativa; three of them (therapeutic massage and Reiki) presented statistically significant results for the management of the cluster pain-anxiety-worry-dyspnea. Most studies presented a moderate risk of bias as per ROBINS-I tool.

CONCLUSION

Therapeutic massage and Reiki may be effective for the symptom clusters management, especially the pain-anxiety-worry-dyspnea cluster in children and adolescents undergoing palliative care.

Effectiveness of hospital clowns for symptom management in paediatrics: systematic review of randomised and non-randomised controlled trials

OBJECTIVE

To evaluate evidence from randomised controlled trials and non-randomised controlled trials on the effectiveness of hospital clowns for a range of symptom clusters in children and adolescents admitted to hospital with acute and chronic conditions.

DESIGN

Systematic review of randomised and non-randomised controlled trials.

DATA SOURCES

Medline, ISI of Knowledge, Cochrane Central Register of Controlled Trials, Science Direct, Scopus, American Psychological Association PsycINFO, Cumulative Index to Nursing and Allied Health Literature, and Latin American and Caribbean Health Sciences Literature.

STUDY SELECTION

Randomised and non-randomised controlled trials were peer reviewed using the following eligibility criteria: children and adolescents who were admitted to hospital for acute conditions or chronic disorders, studies comparing use of hospital clowns with standard care, and studies evaluating the effect of hospital clowns on symptom management of inpatient children and adolescents as a primary outcome.

DATA EXTRACTION AND SYNTHESIS

Two investigators independently screened studies, extracted data, and appraised the risk of bias. Methodological appraisal was assessed by two investigators independently using the Jadad scale, the revised Cochrane risk-of-bias tool for randomised controlled trials (RoB 2), and the risk of bias in non-randomised studies (ROBINS-I) tool for non-randomised controlled trials.

RESULTS

24 studies (n=1612) met the inclusion criteria for data extraction and analysis. Most studies were randomised controlled trials (n=13). Anxiety was the most frequently analysed symptom (n=13), followed by pain (n=9), psychological and emotional responses and perceived wellbeing (n=4), stress (n=4), cancer related fatigue (n=3), and crying (n=2). Five studies used biomarkers, mainly cortisol, to assess stress or fatigue outcome following hospital clowns. Most of the randomised controlled trials (n=11; 85%) were rated as showing some concerns, and two trials were rated with a high risk of bias. Most non-randomised controlled trials (n=6; 55%) were rated with a moderate risk of bias according to ROBINS-I tool. Studies showed that children and adolescents who were in the presence of hospital clowns, either with or without a parent present, reported significantly less anxiety during a range of medical procedures, as well as improved psychological adjustment (P<0.05). Three studies that evaluated chronic conditions showed favourable results for the intervention of hospital clowns with significant reduction in stress, fatigue, pain, and distress (P<0.05).

CONCLUSIONS

These findings suggest that the presence of hospital clowns during medical procedures, induction of anaesthesia in the preoperative room, and as part of routine care for chronic conditions might be a beneficial strategy to manage some symptom clusters. Furthermore, hospital clowns might help improve psychological wellbeing in admitted children and adolescents with acute and chronic disorders, compared with those who received only standard care.

Efficacy of the complementary therapies in the management of cancer pain in palliative care: A systematic review

OBJECTIVE

to synthesize the knowledge and to critically evaluate the evidences arising from randomized controlled trials on the efficacy of the complementary therapies in the management of cancer pain in adult patients with cancer in palliative care.

METHOD

a systematic review guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. The search for articles in the MEDLINE, ISI Web of Knowledge, CENTRAL Cochrane, and PsycINFO databases, as well as the manual search, selection of studies, data extraction, and methodological assessment using the Cochrane Bias Risk tool were performed independently by two reviewers.

RESULTS

eight hundred and fifteen (815) studies were identified, six of them being selected and analyzed, of which three used massage therapy, one study used a combination of progressive muscle relaxation and guided imaging, and another two studies used acupuncture. Most of the studies had an uncertain risk of bias (n=4; 67%).

CONCLUSION

while the evidence from the studies evaluating the use of massage therapy or the use of progressive muscle relaxation and guided imaging for the management of cancer pain in these patients demonstrated significant benefits, the other two studies that evaluated the use of acupuncture as a complementary therapy showed contradictory results, therefore, needing more research studies to elucidate such findings.

Effectiveness of mass testing for control of COVID-19: a systematic review protocol

INTRODUCTION

Since March 2020, when the COVID-19 outbreak has been deemed a pandemic by the WHO, the SARS-CoV-2 spreading has been the focus of attention of scientists, authorities, public health agencies and communities around the world. One of the great concerns and challenges, mainly in low-income and middle-income countries, is the identification and monitoring of COVID-19 cases. The large-scale availability of testing is a fundamental aspect of COVID-19 control, but it is currently the biggest challenge faced by many countries around the world. We aimed to synthesise and critically evaluate the scientific evidence on the influence of the testing capacity for symptomatic individuals in the control of COVID-19.

METHODS AND ANALYSIS

A systematic review will be conducted in eight databases, such as Medical Literature Analysis and Retrieval System Online, ISI-of-Knowledge, Cochrane Central Register of Controlled Trials, Embase, SCOPUS, Latin American and Caribbean Health Sciences Literature, PsycINFO and Chinese National Knowledge Infrastructure, from inception to 30 July 2020. No restriction regarding the language, publication date or setting will be employed. Primary outcomes will include the sensitivity as well as the specificity of the tests for COVID-19. Study selection will follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist. Methodological assessment of the studies will be evaluated by the Cochrane Risk-of-Bias tool for randomised controlled trials, the MINORS for non-randomised studies and the Newcastle-Ottawa Scale for cohort or case-control studies. Findings will be structured according to the test type and target population characteristics and focused on the primary outcomes (sensitivity and specificity). Moreover, if sufficient data are available, a meta-analysis will be performed. Pooled standardised mean differences and 95% CIs will be calculated. Heterogeneity between the studies will be determined by I2 statistics. Subgroup analyses will also be conducted. Publication bias will be assessed with funnel plots and Egger's test. Heterogeneity will be explored by random effects analysis.

ETHICS AND DISSEMINATION

Ethical approval is not required. The results will be disseminated widely via peer-reviewed publication and presentations at conferences related to this field.

Impact of COVID-19 pandemic on mental health of young people and adults: a systematic review protocol of observational studies

INTRODUCTION

Since the WHO declared COVID-19 as a pandemic, the spread of the new coronavirus has been the focus of attention of scientists, governments and populations. One of the main concerns is the impact of this pandemic on health outcomes, mainly on mental health. Even though there are a few empirical studies on COVID-19 and mental health, so far, there is no systematic review about the impact of COVID-19 on mental health of young people and adults yet. We aim to critically synthesise the scientific evidence about the impact of the COVID-19 pandemic on the mental health of young people and adults.

METHODS AND ANALYSIS

A systematic review will be performed through eight databases: MEDLINE (Medical Literature Analysis and Retrieval System Online), ISI-of-Knowledge, CENTRAL (Cochrane Central Register of Controlled Trials), EMBASE (Excerpta Medica Database), SCOPUS, LILACS (Latin American and Caribbean Health Sciences Literature), PsycINFO (Psychology Information) and CNKI (Chinese National Knowledge Infrastructure), from inception until 30 June 2020. No restriction regarding the publication date, setting or languages will be considered. Preliminary search strategies were carried out on 29 March 2020 and will be updated in June 2020. The primary outcomes will be the prevalence and the severity of psychological symptoms in young people and adults (>18 years old) resulting from the impact of COVID-19 pandemic. Study selection will follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist. Pooled standardised mean differences and 95% CIs will be calculated. The risk of bias of the observational studies will be assessed through the Methodological Index for Non-Randomised Studies (MINORS). Additionally, if sufficient data are available, a meta-analysis will be conducted. Heterogeneity between the studies will be determined by the I² statistics. Subgroup analyses will also be performed. Publication bias will be checked with funnel plots and Egger's test. Heterogeneity will be explored by random-effects analysis.

ETHICS AND DISSEMINATION

Ethical assessment was not required. Findings will be disseminated through peer-reviewed publication and will be presented at conferences related to this field.
