Background Due to the disagreement in studies, the present study performed a systematic review and meta-analysis to investigate the relationship between childhood asthma and the development of chronic obstructive pulmonary disease (COPD) in adulthood. Methods Literature search was performed in Medline and Embase databases until the end of 2019. Data were recorded as adjusted odds ratio (OR) and 95% confidence interval (95%CI). Analyses were performed on STATA 14.0 and an overall OR was reported. Subgroup analysis was performed to determine the source of heterogeneity. Results Data from 11 articles were included in the meta-analysis. Overall, the odds of developing adulthood COPD in children with asthma were 3.0 times higher than that in non-asthmatic children (OR = 3.00; 95%CI 2.25-4.00; p less then 0.001). The relationship between childhood asthma and COPD in adulthood was reported somewhat greater in random sampling method studies than consecutive sampling method studies (OR = 2.89; 95% CI 1.72-4.86; p = 0.001). Conclusion Asthma in childhood could be considered as an independent risk factor for COPD in adulthood. Since type of study, sampling method, sample size of study and COPD prevalence are the main sources of heterogeneity, further prospective high-quality studies assessing the relationship of childhood asthma and adulthood COPD are recommended to be performed.Introduction The market for monoclonal antibody (mAb) therapies is growing rapidly as the pharmaceutical industry expands its development across a broad spectrum of diseases. Unfortunately, as shown in the recent failure of bococizumab by Pfizer, these treatments often stimulate the formation of problematic anti-drug antibodies (ADAs). ADAs can cause side effects and limit efficacy for many patients. To increase efficacy and decrease safety concerns from ADAs, immunogenicity characterization is needed early in the drug development process. IDE397 cost Here, we present emerging techniques that hold promise to improve ADA assays and their potential applications to pharmaceutical development and personalized medicine. Areas covered This manuscript outlines the importance of epitope characterization to better understand immunogenicity and describes a strategy for using this information in treating patients taking mAb therapies. Expert opinion We propose using high-information assays to characterize epitopes to help mAb therapy engineering and potentially improve individual patient outcomes. To understand this, we will discuss three different aspects of ADAs (1) the problem of ADAs and what is currently being done about them, (2) the current state of epitope characterization and how it is being utilized, and (3) how early epitope characterization can advance drug discovery and improve outcomes for patients taking mAb therapies.The objective of this study was to evaluate the effects of compound enzymes (CE) (containing per g 375 U amylase, 2500 U protease, 4000 U xylanase and 150 U β-glucanase) on performance, nutrient digestibility, serum antioxidant status, immunoglobulins, intestinal morphology, volatile fatty acids contents and microbiota community in weaned pigs. Seventy-two pigs (Duroc × Landrace × Yorkshire, weaned at d 28) with an average body weight of 8.49 ± 0.87 kg were allotted into two treatments with six replicate pens per treatment (three barrows and three gilts per pen) according to sex and body weight in a randomised complete block design. The treatments contained a corn-soybean meal-barley basal diet (CON) or a basal diet supplemented with 1000 mg CE/kg (CE). The study was divided into phase 1 (d 1 to 14) and 2 (d 15 to 35). The average daily gain was increased (p less then 0.05) in pigs fed CE in phase 2 and overall (d 1 to 35) compared with CON. These pigs had greater (p≤ 0.05) serum IgA, IgG, superoxide dismuts at phylum level, Bacteroidales at the order level, Bacteroidia at class level, Clostridium_sensu_stricto_6 at genus level in colon comp
