Introduction Videolaryngoscope is regarded as the standard of care for airway management in well-resourced setups however the technology is largely inaccessible and costly in middle and low-income countries. An improvised and cost-effective form of customized videolaryngoscope was proposed and studied for patient care in underprivileged areas however there were no distinct conclusions on its performances. Method The study follows PRISMA guidelines for systematic review and the protocol in International Prospective Register for Systematic Reviews. The primary aim was to assess the first attempt success of customized videolaryngoscope for endotracheal intubation. The secondary objective was to evaluate the number of attempts, laryngoscopic view in terms of Cormack Lehane score and Percentage of glottic opening, use of external laryngeal maneuver and stylet and, the airway injuries after the endotracheal intubation. Result Five studies were analyzed for risk of bias using the National Institute of Health Quality Assessment Tool for cross-sectional studies. Most of the studies had a poor to a fair level of evidence with only one study with a good level of evidence. Certainty of evidence was “very low” for all eligible studies when graded using the Grading of Recommendation, Assessment, Development and Evaluation approach for systematic review. Conclusions The certainty of the evidence regarding performance of custom-made videolaryngoscope compared to conventional laryngoscope was very low and the study was performed in small numbers with fair to the poor risk of bias. It was difficult to establish and do further analysis regarding whether the customized form of videolaryngoscope will improve the first attempt success rate for tracheal intubation, reduce the number of attempts, improve the laryngoscopic view, require fewer external aids and reduce the incidences of airway injury with the given low-grade evidence. Some properly conducted randomised clinical trials will be required to further analyze the outcome and make the strong recommendations.

BackgroundAlthough surgical site infection (SSI) is one of the most studied healthcare-associated infections, the global burden of SSI after appendectomy remains unknown.ObjectiveWe estimated the incidence of SSI after appendectomy at global and regional levels.DesignSystematic review and meta-analysis.ParticipantsAppendectomy patients.Data sourcesEMBASE, PubMed and Web of Science were searched, with no language restrictions, to identify observational studies and clinical trials published between 1 January 2000 and 30 December 2018 and reporting on the incidence of SSI after appendectomy. A random-effect model meta-analysis served to obtain the pooled incidence of SSI after appendectomy.ResultsIn total, 226 studies (729 434 participants from 49 countries) were included in the meta-analysis. With regard to methodological quality, 59 (26.1%) studies had low risk of bias, 147 (65.0%) had moderate risk of bias and 20 (8.8%) had high risk of bias. We found an overall incidence of SSI of 7.0 per 100 appendectomies (95% prediction interval: 1.0–17.6), varying from 0 to 37.4 per 100 appendectomies. A subgroup analysis to identify sources of heterogeneity showed that the incidence varied from 5.8 in Europe to 12.6 per 100 appendectomies in Africa (p<0.0001). The incidence of SSI after appendectomy increased when the level of income decreased, from 6.2 in high-income countries to 11.1 per 100 appendectomies in low-income countries (p=0.015). Open appendectomy (11.0 per 100 surgical procedures) was found to have a higher incidence of SSI compared with laparoscopy (4.6 per 100 appendectomies) (p=0.0002).ConclusionThis study suggests a high burden of SSI after appendectomy in some regions (especially Africa) and in low-income countries. Strategies are needed to implement and disseminate the WHO guidelines to decrease the burden of SSI after appendectomy in these regions.Prospero registration numberCRD42017075257.

BackgroundWhile it is now apparent clinical sequelae (long COVID) may persist after acute COVID-19, their nature, frequency and aetiology are poorly characterised. This study aims to regularly synthesise evidence on long COVID characteristics, to help inform clinical management, rehabilitation strategies and interventional studies to improve long-term outcomes.MethodsA living systematic review. Medline, CINAHL (EBSCO), Global Health (Ovid), WHO Global Research on COVID-19 database, LitCovid and Google Scholar were searched till 17 March 2021. Studies including at least 100 people with confirmed or clinically suspected COVID-19 at 12 weeks or more post onset were included. Risk of bias was assessed using the tool produced by Hoy et al. Results were analysed using descriptive statistics and meta-analyses to estimate prevalence.ResultsA total of 39 studies were included: 32 cohort, 6 cross-sectional and 1 case–control. Most showed high or moderate risk of bias. None were set in low-income countries and few included children. Studies reported on 10 951 people (48% female) in 12 countries. Most included previously hospitalised people (78%, 8520/10 951). The longest mean follow-up time was 221.7 (SD: 10.9) days post COVID-19 onset. Over 60 physical and psychological signs and symptoms with wide prevalence were reported, most commonly weakness (41%; 95% CI 25% to 59%), general malaise (33%; 95% CI 15% to 57%), fatigue (31%; 95% CI 24% to 39%), concentration impairment (26%; 95% CI 21% to 32%) and breathlessness (25%; 95% CI 18% to 34%). 37% (95% CI 18% to 60%) of patients reported reduced quality of life; 26% (10/39) of studies presented evidence of reduced pulmonary function.ConclusionLong COVID is a complex condition with prolonged heterogeneous symptoms. The nature of studies precludes a precise case definition or risk evaluation. There is an urgent need for prospective, robust, standardised, controlled studies into aetiology, risk factors and biomarkers to characterise long COVID in different at-risk populations and settings.PROSPERO registration numberCRD42020211131.

BACKGROUND: Acute normovolemic hemodilution (ANH) has been proposed as a microsurgical technique to improve blood flow in free flaps. OBJECTIVE: Here, we present the first systematic review of clinical and experimental studies on the effect of ANH. METHODS: We performed a systematic literature search of PubMed, Medline, the Cochrane Library, Google Scholar, and ClinicalTrials.gov using search strategies and a review process in agreement with the PRISMA statement and the Cochrane Handbook for systematic reviews of interventions. PICO criteria were defined before bibliometric processing of the retrieved articles, which were analyzed with the SYRCLE RoB tool for risk of bias and the GRADE scale for level of evidence. RESULTS: We retrieved 74 articles from the literature search, and after processing according to PICO criteria, only four articles remained, all of which were experimental. The rating for risk of bias was uncertain according to SYRCLE RoB results, and the level of evidence was low according to GRADE evaluation. CONCLUSIONS: There is no clinical evidence for the effect of ANH on microcirculation in free flaps, and experimental studies provide weak evidence supporting the use of hemodilution in reconstructive microsurgery.

Context: Since the onset of the COVID-19 pandemic, there have been numerous higher education challenges. Medical universities have been urged to dispel students from educational and clinical settings and led them toward virtual education. This sudden transition has been accompanied by multiple challenges. Objectives: The present study aimed to evaluate the challenges of virtual medical education in the COVID-19 pandemic. Study Selection: This systematic review was performed by reviewing the current literature on the research subject and the studies conducted in this regard during March 2019 to April 2021 by searching via five key search engines and databases, including Google Scholar, ScienceDirect, PubMed, Scopus, and ERIC. Results: In total, 23 studies were assessed, and different virtual education challenges in medical universities were classified into three categories of structural challenges, student-related challenges, and teacher-related challenges. In addition, strategies were proposed for overcoming the identified challenges. Conclusions: Since medical education was not properly pursued before the COVID-19 pandemic and the necessary infrastructures are lacking in this area, designing and implementing such programs could bring about fundamental challenges in several countries (especially developing and low-income countries), thereby decreasing their success rate. On the other hand, the coronavirus crisis could be an opportunity to identify the weaknesses, shortcomings, and infrastructural deficiencies in e-learning and address these issues effectively.

Background Though cervical cancer is one of the leading causes of death globally, its incidence is nearly entirely preventable. Young people have been an international priority for screening. However, in both high-income and low-income countries, young people have not been screened appropriately according to country-specific guidelines and in many countries, screening rates for this age-group have even dropped. Objectives The aim of this systematic review was to systematically characterize the existing literature on barriers and facilitators for cervical cancer screening among young people globally. Search Strategy We conducted a systematic review following PRISMA guidelines of four databases: Medline-OVID, EMBASE, CINAHL, and ClinicalTrials.Gov. Selection Criteria We only examined original, peer-reviewed literature. Databases were examined from inception until the date of our literature searches (12/03/2020). Articles were excluded if they did not specifically discuss cervical cancer screening, were not specific to young people, or did not report outcomes or evaluation. Data Collection and Analysis All screening and extraction was completed in duplicate with two independent reviewers. Main Results Of the 2177 original database citations, we included 36 studies that met inclusion criteria. Our systematic review found that there are three large categories of barriers for young people: lack of knowledge/awareness, negative perceptions of the test, and practical barriers to testing. Facilitators included stronger relationships with healthcare providers, social norms, support from family, and self-efficacy. Conclusions Health systems worldwide should address the barriers and facilitators to increase cervical cancer screening rates in young people. Further research is required to understand this age group.

Objective. The aim was to assess the clinical effectiveness of drugs used in hospitalized patients with COVID-19 infection. Method. We conducted a systematic review of randomized clinical trials assessing treatment with remdesivir, chloroquine, hydroxychloroquine, lopinavir, ritonavir, dexamethasone, and convalescent plasma, for hospitalized patients with a diagnosis of SARS-CoV-2 infection. The outcomes were mortality, clinical improvement, duration of ventilation, duration of oxygen support, duration of hospitalization), virological clearance, and severe adverse events. Results. A total of 48 studies were retrieved from the databases. Ten articles were finally included in the data extraction and qualitative synthesis of results. The meta-analysis suggests a benefit of dexamethasone versus standard care in the reduction of risk of mortality at day 28; and the clinical improvement at days 14 and 28 in patients treated with remdesivir. Conclusions. Dexamethasone would have a better result in hospitalized patients, especially in low-resources settings. Significance of results. The analysis of the main treatments proposed for hospitalized patients is of vital importance to reduce mortality in low-income countries; since the COVID-19 pandemic had an economic impact worldwide with the loss of jobs and economic decline in countries with scarce resources. Keywords: Drugs; Antivirals; Clinical improvement; Mortality; COVID-19; SARS-CoV2.

The unsustainable food consumption across high-income countries (HICs) and low-income countries (LICs) is expected to differ in nature and extent, although no formal evidence in this respect has been documented. Documenting this evidence is the aim of this chapter. Specifically, the chapter seeks to answer the following questions: 1) Do the contexts in less developed countries (LDCs) and developed countries (DCs) make the nature and extent of unsustainability in food consumption different? 2) Do the mechanisms of the linkage between unsustainability of food consumption and health outcomes independent of countries' contexts? 3) Are current policies against unsustainable food consumption equally effective in DCs and LDCs? These questions are answered by means of a systematic review of the literature for the period 2000-2017. The findings are that the nature and extent of unsustainability is quite different across contexts of LICs and HICs.
