Evidence based medicine is at the core of modern medicine. It involves the integration of individual clinical expertise with the best available clinical evidence from systematic research and patient's values and expectations. Systematic reviews offer a summary of the best available evidence. They are the most reliable and comprehensive statement about what works. Written by clinical academics from Australia, UK, USA, and Switzerland, this contributed volume introduces the readers to the principles and practice of systematic reviews and meta-analysis. It covers the various steps involved in systematic reviews including development of a focused question and the strategy for conducting a comprehensive literature search, identifying studies addressing the underlying question, assessment of heterogeneity and the risk of bias in the included studies, data extraction, and the approach to meta-analysis. Crucial issues such as selecting the model for meta-analysis, generating and interpreting forest plots, assessing the risk of publication bias, cautions in the interpretation of subgroup and sensitivity analyses, rating certainty of the evidence using GRADE guideline, and standardized reporting of meta-analysis (PRISMA) are covered in detail. Every attempt is made to keep the narrative simple and clear. Mathematical formulae are avoided as much as possible. While the focus of this book is on systematic reviews and meta-analyses of randomised controlled trials (RCTs), the gold standard of clinical research, the essentials of systematic reviews of non-RCTs, diagnostic test accuracy studies, animal studies, individual participant data meta-analysis, and network meta-analysis are also covered. Readers from all faculties of medicine will enjoy this comprehensive and reader friendly book to understand the principles and practice of systematic reviews and meta-analysis for guiding their clinical practice and research.

This book is a collection of state-of-the-art reviews on the various aspects of nutrition for the preterm neonate, by internationally renowned clinicians and researchers from Australia, UK, USA, Canada, and Italy. It provides the scientific basis and clinical perspective on the A to Z of enteral and parenteral nutrition for extremely preterm neonates, making it valuable for all involved in the care of this high-risk population. The topics covered range from the developmental physiology of the gastrointestinal tract, and early trophic feeds, to aggressive enteral and parenteral nutrition, and feeding under special conditions such as intrauterine growth restriction and chronic lung disease. Survival of extremely preterm neonates has improved significantly following the advances in neonatal intensive care. Extrauterine growth restriction is recognised as a serious and almost universal issue in this population. Considering the long term consequences of nutritional deficit and poor growth (e.g. neurodevelopmental impairment, short stature and metabolic disorders), optimising nutrition in the early postnatal life of the preterm neonate is crucial. However this is easier said than done considering the frequency of feed intolerance, fear of necrotising enterocolitis, and the hesitancy in adopting an aggressive approach to parenteral nutrition in this population. The simple and practical approach of this comprehensive and unique book makes it a must read for clinicians as well as researchers involved in neonatal intensive care. It is a useful resource for trainees in neonatology, paediatric gastroenterology, and neonatal nursing, and also for dieticians specialising in neonatal nutrition.

Survival of extremely premature neonates has improved significantly following the advances in neonatal intensive care. Extrauterine growth restriction is a serious issue in this population. Nutritional exposures during critical period of life influence the individual's risk of disease throughout life. Nutritional deficit and poor growth are associated with long term neurodevelopmental impairment, short stature and metabolic disorders in extremely preterm neonates. Optimising nutrition in the early postnatal life of the preterm neonate is therefore a priority. However this is easier said than done considering the frequency of feed intolerance, fear of necrotising enterocolitis, and the hesitancy in adopting an aggressive approach to parenteral nutrition in this population. Some of the finest researchers in the field have come together to provide the clinical perspective on the A to Z of nutrition in the preterm neonate in simple and clear fashion in this book.

This book will provide anyone with an interest in the clinic with a basic guide on those things that are not taught during medical school or any other pre-clinical trainings. The line-up of authors was carefully assembled to include experts in all respective fields to give this volume the authority it requires to be a relevant text for many.
