Letter to the editor: Backdrop context of the study "Intention to vaccinate young children against COVID-19: a large-scale survey of Hong Kong parents".

The current letter provides the backdrop context of the study "Intention to vaccinate young children against COVID-19: a large-scale survey of Hong Kong parents" conducted when the COVID-19 vaccination was first made available to young children in Hong Kong during the fifth wave of the outbreak. The study was conducted to examine parents' intention for informing the development of an effective child COVID-19 vaccine program because parents were speculated to have low intention to vaccinate their children against COVID-19.

Intention to vaccinate young children against COVID-19: A large-scale survey of Hong Kong parents.

COVID-19 vaccines (Sinovac and Pfizer/BioNTech) have recently been approved for Hong Kong children. Understanding parental intentions to vaccinate children against COVID-19 is important to the development of an effective COVID-19 vaccine campaign. From a large-scale, geographically representative dataset in Hong Kong ( = 11,141), we examined parents' intentions to vaccinate their children against COVID-19 under three conditions: (1) no policy restrictions, (2) vaccination rate considered for school resumption, and (3) more choices of vaccine.

Correction of severe hyponatremia by continuous veno-venous hemodialysis with regional citrate anticoagulation: A case series.

Introduction: Hyponatremia is a common electrolyte disturbance in critically ill patients. Management of intensive care unit patients with concurrent hyponatremia and renal failure requiring dialysis is challenging especially with regional citrate anticoagulation, which may cause excessive rise of serum [Na ]. We described the first and successful modified continuous veno-venous hemodialysis (CVVHD) regimen using regional citrate anticoagulation.

Treatment of Acute Kidney Injury Complicating Septic Shock with EMiC2 High-cutoff Hemofilter: Case Series.

Introduction: Extracorporeal blood purification therapies have been proposed to improve outcomes of patients with severe sepsis, with or without accompanying acute kidney injury (AKI), by removal of excessive inflammatory mediators.

Materials And Methods: We report our experience with EMiC2 high-cutoff continuous venovenous hemofiltration/hemodialysis (HCO-CVVH/HD) in seven patients with AKI complicating septic shock.

Results: The median treatment duration was 71 h, and the procedure was well tolerated.

Impact of renal replacement therapy on survival in patients with KDIGO stage 3 acute kidney injury: A propensity score matched analysis.

Aim: To investigate the impact of renal replacement therapy (RRT) on 90-day mortality in critically ill patients suffering from KDIGO stage 3 acute kidney injury (AKI) with or without life-threatening complications using propensity score matching analysis.

Methods: We conducted a retrospective analysis of critically ill adult patients with KDIGO Stage 3 AKI with or without RRT during ICU stay between 1/1/2011-31/12/2013. Cox regression analysis and propensity score matching methods were used to determine predictors for 90-day mortality.

Preoperative red cell distribution width: Not a useful prognostic indicator for 30-day mortality in patients who undergo major- or ultra-major noncardiac surgery.

Background: Red cell distribution width (RDW) has been shown to be associated with mortality in cardiac surgical patients. This study investigates the association of RDW with the 30-day mortality for those patients who undergo major- or ultra-major noncardiac surgery.

Methods: Patients who received major- or ultra-major noncardiac surgery between July 2012 and May 2013 were included in the study and patients those with preoperative hemoglobin <10 g/day were excluded from the study.

Septic acute kidney injury in critically ill patients - a single-center study on its incidence, clinical characteristics, and outcome predictors.

Purpose The objective of this study is to examine the incidence, clinical characteristics, and outcome (90-day mortality) of critically ill Chinese patients with septic AKI. Methods Patients admitted to the ICU of a regional hospital from 1 January 2011 to 31 December 2013 were included, excluding those on chronic renal replacement therapy. AKI was defined using KDIGO criteria.

Predictive value of plasma neutrophil gelatinase-associated lipocalin for acute kidney injury in intensive care unit patients after major non-cardiac surgery.

Aim: The performance of plasma neutrophil gelatinase-associated lipocalin (pNGAL) for prediction of acute kidney injury (AKI) in non-cardiac surgical patients has not been well described. This study investigates the use of pNGAL for early detection of AKI in patients admitted to an intensive care unit (ICU) after major or ultra-major non-cardiac surgery.

Methods: A total of 151 patients were recruited.

Alteco endotoxin hemoadsorption in Gram-negative septic shock patients.

Background And Aims: Severe sepsis and septic shock are common causes of mortality and morbidity in an intensive care unit setting. Endotoxin, derived from the outer membranes of Gram-negative bacteria, is considered a major factor in the pathogenesis of sepsis. This study investigated the effect of Alteco endotoxin hemoadsorption device on Gram-negative septic shock patients.

The use of regional citrate anticoagulation continuous venovenous hemofiltration in extracorporeal membrane oxygenation.

Patients on extracorporeal membrane oxygenation (ECMO) frequently requires continuous renal replacement therapy (CRRT). Additional anticoagulation for the CRRT circuit is usually not employed, but this may increases the risk of clot embolization, which shortens oxygenator lifespan and increases patient's risk. We report our experience on the use of regional citrate anticoagulation continuous venovenous hemofiltration (RCA-CVVH) connected to an ECMO circuit, which could be useful during low heparin or heparin-free ECMO situations.

Timing for initiation of continuous renal replacement therapy in patients with septic shock and acute kidney injury.

The optimal timing for renal replacement therapy initiation in septic acute kidney injury (AKI) remains controversial. This study investigates the impact of early versus late initiation of continuous renal replacement therapy (CRRT) on organ dysfunction among patients with septic shock and AKI. Patients were dichotomized into "early" (simplified RIFLE Risk) or "late" (simplified RIFLE Injury or Failure) CRRT initiation.

A retrospective review of the use of regional citrate anticoagulation in continuous venovenous hemofiltration for critically ill patients.

Background. The emergence of a commercially prepared citrate solution has revolutionized the use of RCA in the intensive care unit (ICU). The aim of this study was to evaluate the safety profile of a commercially prepared citrate solution.

Regional citrate anticoagulation in predilution continuous venovenous hemofiltration using prismocitrate 10/2 solution.

Regional citrate anticoagulation (RCA) for continuous renal replacement therapy (CRRT) is associated with a longer filter life and fewer bleeding events. Complexity of the regimen is the major hurdle preventing widespread application. This study describes a simple predilution continuous venovenous hemofiltration (CVVH) protocol utilizing a commercially prepared replacement solution containing citrate (Prismocitrate 10/2).

Interaction between fluid balance and disease severity on patient outcome in the critically ill.

Purpose: There is evidence in literature regarding the benefits of immediate aggressive fluid resuscitation together with conservative fluid management approach after initial stabilization. This retrospective study assesses the relationship between fluid balance during intensive care unit (ICU) stay and outcomes among general critically ill patients. In addition, we also aim to see the effect of fluid gain among patients with different disease severity.

Triage decisions and outcomes for patients with Triage Priority 3 on the Society of Critical Care Medicine scale.

Objective: To identify factors associated with the triage decision for patients classified as Society of Critical Care Medicine (SCCM) Triage Priority 3, and their outcomes.

Design: Single-centre, prospective, observational cohort study.

Setting: General intensive care unit in a tertiary regional hospital, over the 9 months January to September 2007.
