    Abstract Endoscopic submucosal dissection (ESD) is an advanced endoscopic procedure for management of gastrointestinal tumours. ESD is usually performed under sedation. However, the use of general anaesthesia (GA) has been hypothesised to improve ESD outcomes. We performed a systematic review and meta-analysis to compare GA against sedation in ESD. A systematic literature search was performed on Cochrane Library, EMBASE and MEDLINE using the terms "General Anaesthesia", "Sedation" and "Endoscopic submucosal dissection". Original articles comparing GA versus sedation in ESD were included. The risk of bias and level of evidence were assessed by validated methods. This review is registered in PROSPERO (CRD42021275813). 176 articles were found in the initial literature search, and 7 articles (comprising 518 patients receiving GA and 495 receiving sedation) were included. Compared with sedation, GA was associated with higher en-bloc resection rates in oesophageal ESD (RR 1.05; 95% CI: 1.00-1.10; I 2 = 65%; P = 0.05). GA patients also trended towards lower rates of gastrointestinal perforation in all ESD procedures (RR 0.62; 95% CI: 0.21-1.82; I 2 = 52%; P = 0.06). Rates of intra- procedural desaturation and post-procedural aspiration pneumonia were lower in GA patients than in patients under sedation. The included studies had a moderate to high risk of bias, and the overall level of evidence was low. GA appears safe and feasible for ESD, yet high-quality trials will be required before GA can be regularly implemented for ESD.

    Abstract Asthma is the most prevalent chronic disease in children. Inhaled corticosteroids (ICS) is the first-line controller therapy for children with persistent asthma, however, suboptimal compliance to ICS therapy remains as a major obstacle in paediatric asthma management. Steroid-phobia, the fear of side-effects and subsequent aversion of ICS, has been widely reported in parents of asthmatic children. The reported prevalence of steroid-phobia varies widely from 19% to 67% in different populations. The concerns about ICS frequently raised by parents include growth suppression, weight gain, bone weakness, addiction and psychiatric disturbances. Outside of growth suppression, which is statistically significant yet mild in clinical studies, the other concerns are not evidence-based and are misconceptions. Conflicting results have been reported regarding the impact of steroid-phobia on ICS compliance. In contrast, steroid-phobia has consistent and negative effects on asthma control in children. While asthma educational programmes have demonstrable benefits in general paediatric populations, the generalisability of such programmes to steroid-phobic parents remains undetermined. There is a paucity of data on specific educational programmes to clear misconceptions and reduce steroid-phobia. Given the continually raising prevalence of paediatric asthma, high-quality studies are warranted to investigate the prevalence and impact of steroid-phobia, with an ultimate goal of developing effective strategies to tackle steroid-phobia and improve asthma care in children.

    Abstract Background: Transesophageal echocardiography (TEE) is useful for cardiac assessment and intraoperative monitoring. However, the safety of TEE in patients with cirrhosis and gastroesophageal varices has remained uncertain. The aim of this meta-analysis was to determine the incidence of gastrointestinal bleeding after TEE in patients with varices. The secondary objectives were to compare bleeding risks between patients with and without varices and to determine the incidence of TEE-related esophageal perforation and mortality.
    Methods: A systematic literature search was conducted on MEDLINE, Embase, and the Cochrane Library using the terms "transesophageal echocardiography," "varices," "bleeding," and related terms. Articles describing the incidence of post-TEE bleeding in patients with varices were included. Non-English-language articles were excluded. Risk of bias and level of evidence were assessed using validated scales. The pooled weighted incidence of gastrointestinal bleeding and the risk difference in bleeding were calculated using a random-effects model.
    Results: Five hundred and sixty-nine articles were identified initially, and 10 articles (comprising of 908 patients) were included. The incidence of post-TEE bleeding in patients with varices was 0.84% (95% CI, 0.34% to 1.56%). When stratified by indication for TEE, the pooled incidence of bleeding was 0.68% (95% CI, 0.11% to 1.63%) for intraoperative TEE and 1.03% (95% CI, 0.23% to 2.29%) for diagnostic TEE. No cases of esophageal perforation or mortality were reported. Six studies included comparator groups of patients without varices, and the bleeding risk was comparable between patients with and those without varices (risk difference, 0.26%; 95% CI, -0.80% to 1.32%; I
    Conclusions: TEE appears to be associated with low gastrointestinal bleeding incidence in patients with gastroesophageal varices. Nonetheless, results should be treated with caution because of bias and low level of evidence. Large-scale high-quality studies will be required to confirm the safety of TEE in patients with gastroesophageal varices.

    Abstract Chronic hepatitis B infection is a major public health challenge. With the advancement in technology, various components of the viral cycle can now be measured in the blood to assess viral activity. In this review article, we summarize the relevant data of how antiviral therapies impact viral biomarkers, and discuss their potential implications. Viral nucleic acids including hepatitis B virus (HBV) double-stranded deoxy-ribonucleic acid (DNA) and to a lesser extent, pre-genomic RNA, are readily suppressed by nucleos(t)ide analogues (NUCs). The primary role of these markers include risk prediction for hepatocellular carcinoma (HCC) and risk stratification for partial cure, defined as off-therapy virological control, or functional cure, defined as hepatitis B surface antigen (HBsAg) seroclearance plus undetectable serum HBV DNA for ≥6 months. Viral translational products including hepatitis e antigen, quantitative HBsAg and hepatitis B core-related antigen can be reduced by NUCs and pegylated interferon a. They are important in defining disease phase, delineating treatment endpoints, and predicting clinical outcomes including HCC risk and partial/ functional cure. As the primary outcome of phase III trials in chronic hepatitis B is set as HBsAg seroclearance, appropriate viral biomarkers can potentially inform the efficacy of novel compounds. Early viral biomarker response can help with prioritization of subjects into clinical trials. However, standardization and validation studies would be crucial before viral biomarkers can be broadly implemented in clinical use.

    Abstract Patient-controlled sedation (PCS) has been explored as a sedation method in endoscopic retrograde cholangiopancreatography (ERCP), yet a comprehensive review article on this topic is lacking. We performed a systematic review to compare PCS against clinician-administered sedation. The primary objectives are to compare the sedative dosage used and the sedation depth, while secondary objectives are to compare sedation failure rates, clinician intervention rates, and patient satisfaction. A systematic literature search was conducted on MEDLINE, EMBASE, and the Cochrane Library Database using the terms "ERCP," "Sedation," "Patient-controlled," and related terms. Randomized controlled trials comparing PCS against clinician-administered sedation in adults undergoing ERCP were included. Articles without English full texts were excluded. Studies were reviewed by 2 independent reviewers. The Cochrane Risk of Bias tool was used for quality assessment of individual included trials. This systematic review is registered in the International Prospective Register of Systematic Reviews (CRD42020198647). A total of 2619 articles were identified from the literature search. A total of 2615 articles were excluded based on the exclusion criteria. Four articles (comprised of 4 independent trials involving 425 patients) were included in analysis. When compared with clinician-administered sedation, PCS in ERCP may lead to lower propofol dosage used and lower sedation depth. The sedation failure rates appear to be higher in PCS, whereas lower rates of airway maneuvers are required. No significant difference was observable for patient satisfaction rates between PCS and clinician-administered sedation. The included studies demonstrated unclear to high risk of bias, particularly in randomization, incomplete outcome data, and outcome measurement. PCS appears to be a feasible option for sedation in ERCP. Nonetheless, large-scale, high-quality trials will be required before PCS can be regularly implemented in ERCP.
