Abstract
OBJECTIVES To explore the effect of two different priming strategies (artificial colloid only vs. artificial colloid combined with human serum albumin) on the prognosis of children weighing less than 5 kg undergoing on-pump congenital heart disease (CHD) surgery. METHODS A total of 65 children weighing less than 5 kg who underwent on-pump CHD surgery in our hospital from September 2016 to December 2017 were enrolled in this study. The children were randomly divided into two groups: artificial colloid priming group (AC group, n=33) and artificial colloid combined albumin priming group (ACA group, n=32). The primary clinical endpoint was the peri-CPB colloid osmotic pressure (COP). Secondary clinical endpoints included perioperative blood product & hemostatic drug consumption, postoperative renal function, coagulation function, postoperative renal function and postoperative recovery parameters. RESULTS COP values were not significant in the priming system as well as peri-CPB time points between the two groups (P>0.05). Platelet consumption in the AC group was significantly lower than that in the ACA group (P<0.05). There were no significant differences in the use of other blood products and hemostatic drugs as well as perioperative coagulation parameters between the two groups (P>0.05). Postoperative length of stay in the AC group was significantly lower than that in the ACA group (P<0.05). There were no significant differences in mortality, postoperative mechanical ventilation time, ICU time and perioperative adverse event (including postoperative AKI) occurrences between the two groups (P>0.05). CONCLUSIONS In the on-pump cardiac surgeries of patients weighting less than 5kg, total colloidal priming would not affect peri-CPB COP values, postoperative coagulation function and blood products consumption. Total artificial colloidal priming strategy is feasible in low-weight patients.

Intravenous immunoglobulins for Alzheimer's disease and mild cognitive impairment due to Alzheimer's disease: a systematic review with meta-analysis

Expert review of neurotherapeutics. 2019
Abstract
INTRODUCTION Alzheimer's disease (AD) is the most common phenotype of dementia. Mild cognitive impairment (MCI) due to AD is believed as a prodromal stage of AD. Intravenous immunoglobulin (IVIG) is a classical immunotherapy and potentially reduces AD-type pathology by anti-Abeta, anti-tau, anti-inflammatory effects and non-antibody-mediated effects. Areas covered: The authors aimed to determine the efficacy and safety of IVIG for AD and MCI due to AD patients. The electronic databases including PubMed, EMBASE, CINAHL, Cochrane Library and China National Knowledge Infrastructure were searched until March 2019. The results were pooled via a random-effects model. There were five eligible studies with 772 randomized patients with AD and MCI due to AD, which compared IVIG with placebo. Expert opinion: No significant differences were found in the scores of mini-mental state examination and Alzheimer's disease assessment scale-cognitive subscale and number of patients with adverse events. IVIG is well-tolerated in the patients with AD and MCI due to AD, even in long-term therapy for 18 months. Insufficient evidences support IVIG in the treatment of patients with AD and MCI due to AD to improve cognition or disease modification. Well-designed randomized controlled trials with large sample sizes are required in the future.

Abstract
BACKGROUND Hepatitis is a viral infection of the liver. It is mainly transmitted between people through contact with infected blood, frequently from mother to baby in-utero. Hepatitis B poses significant risk to the fetus and up to 85% of infants infected by their mothers at birth develop chronic hepatitis B virus (HBV) infection. Hepatitis B immunoglobulin (HBIG) is a purified solution of human immunoglobulin that could be administered to the mother, newborn, or both. HBIG offers protection against HBV infection when administered to pregnant women who test positive for hepatitis B envelope antigen (HBeAg) or hepatitis B surface antigen (HBsAg), or both. When HBIG is administered to pregnant women, the antibodies passively diffuse across the placenta to the child. This materno-fetal diffusion is maximal during the third trimester of pregnancy. Up to 1% to 9% infants born to HBV-carrying mothers still have HBV infection despite the newborn receiving HBIG plus active HBV vaccine in the immediate neonatal period. This suggests that additional intervention such as HBIG administration to the mother during the antenatal period could be beneficial to reduce the transmission rate in utero. OBJECTIVES To determine the benefits and harms of hepatitis B immunoglobulin (HBIG) administration to pregnant women during their third trimester of pregnancy for the prevention of mother-to-child transmission of hepatitis B virus infection. SEARCH METHODS We searched the The Cochrane Hepato-Biliary Group Controlled Trials Register, CENTRAL, MEDLINE Ovid, Embase Ovid, Science Citation Index Expanded (Web of Science), SCOPUS, African Journals OnLine, and INDEX MEDICUS up to June 2016. We searched ClinicalTrials.gov and portal of the WHO International Clinical Trials Registry Platform (ICTRP) in December 2016. SELECTION CRITERIA We included randomised clinical trials comparing HBIG versus placebo or no intervention in pregnant women with HBV. DATA COLLECTION AND ANALYSIS Two authors extracted data independently. We analysed dichotomous outcome data using risk ratio (RR) and continuous outcome data using mean difference (MD) with 95% confidence intervals (CI). For meta-analyses, we used a fixed-effect model and a random-effects model, along with an assessment of heterogeneity. If there were statistically significant discrepancies in the results, we reported the more conservative point estimate. If the two estimates were equal, we used the estimate with the widest CI as our main result. We assessed bias control using the Cochrane Hepato-Biliary Group suggested bias risk domains and risk of random errors using Trial Sequential Analysis (TSA). We assessed the quality of the evidence using GRADE. MAIN RESULTS All 36 included trials originated from China and were at overall high risk of bias. The trials included 6044 pregnant women who were HBsAg, HBeAg, or hepatitis B virus DNA (HBV-DNA) positive. Only seven trials reported inclusion of HBeAg-positive mothers. All 36 trials compared HBIG versus no intervention. None of the trials used placebo.Most of the trials assessed HBIG 100 IU (two trials) and HBIG 200 IU (31 trials). The timing of administration of HBIG varied; 30 trials administered three doses of HBIG 200 IU at 28, 32, and 36 weeks of pregnancy. None of the trials reported all-cause mortality or other serious adverse events in the mothers or babies. Serological signs of hepatitis B infection of the newborns were reported as HBsAg, HBeAg, and HBV-DNA positive results at end of follow-up. Twenty-nine trials reported HBsAg status in newborns (median 1.2 months of follow-up after birth; range 0 to 12 months); seven trials reported HBeAg status (median 1.1 months of follow-up after birth; range 0 to 12 months); and 16 trials reported HBV-DNA status (median 1.2 months of follow-up; range 0 to 12 months). HBIG reduced mother-to-child transmission (MTCT) of HBsAg when compared with no intervention (179/2769 (6%) with HBIG versus 537/2541 (21%) with no intervention; RR 0.30, TSA-adjusted CI 0.20 to 0.52; I2 = 36%; 29 trials; 5310 part
