Giardiasis is one of the most common gastrointestinal parasitic diseases worldwide and it is caused by an enteric pathogen named Giardia spp. Giardiasis is the most commonly reported human parasite of gastroenteritis with frequent sporadic cases and community-wide outbreaks via water- and -in smaller proportion- foodborne pathways. Giardiasis encompasses a complex and diverse spectrum of symptom patterns ranging from asymptomatic carriage to acute and chronic health states. Prolonged chronic infections eau enhance extra-intestinal and post-infectious sequelae. Estimation of the population health status, also known as "disease burden", requires well-defined information on clinical outcomes of infection. Unfortunately, regarding the diverse symptomatology and limited knowledge on pathogenesis mechanisms, giardiasis burden is often difficult to estimate and report. Objectives: To accurately estimate the disease burden of giardiasis and explain satisfactory its clinical impact, it is therefore necessary to have information on the nature and frequency of these sequelae. To this end, we aim to be able to get a better understanding of the symptoms of Giardia infection in humans. The aim of this thesis will be to review the clinical impact of giardiasis worldwide using a systematic search approach. To this end we will proceed in a two-step approach as follows: 1.First we will review existing assessments of the disease burden of Giardia. This will give an overview of the current disease models (i.e., lists of giardiasis symptoms .2.Next we will perform a systematic review of clinical symptoms associated with Giardia infection in humans in order to identify the health states which are associated with the giardiasis burden and estimate the occurrence of potential sequelae (acute and chronic) of giardiasis. Methods: In order to address the identified gaps, we chose to perform systematic review of the literature according to PRISMA guidelines. We will focus on prospective studies (i.e., cohort studies, longitudinal studies and outbreak investigations) retrospective studies (i.e., case-control studies) and cross-sectional studies. Findings: To date, we have irrefutable evidence of variability in clinical outcomes associated with Giardia infection. Typically assumed as a re-emerging and neglected disease, giardiasis places a heavy burden in both developed and developing countries. It has been linked to persistent diarrhoea that may contribute to substantial weight loss, retardation of growth and development in infants, cognitive impairment and malabsorption. In addition, it has been confirmed that acute giardiasis is associated with significant post-infectious chronic sequelae in adults such as imitable bowel syndrome, chronic fatigue or functional dyspepsia. These persistent sequelae affect the quality of life by continuing to inflict on patients long lasting discomfort and pain.

Root Cause Failure Analysis (RCFA) is a method used by maintenance and reliability industry professionals as one of the key tools to drive improvement. This book offers a quick guide to the applications involved in performing a successful RCFA by providing a foundational view of maintenance and reliability strategies. It also highlights the practical applications of RCFA and identifies how to achieve a successful RCFA, as well as discussing common equipment failures and how to solve them. Case studies on topics including pump system failure analysis and vibration analysis are included. Suggests examples on how to solve common failure on many types of equipment, including fatigue, pumps, bearings, and mechanical power transmission Highlights practical applications of RCFA Identifies key elements for how to achieve a successful RCFA Presents case studies on topics including pump system failure analysis and vibration analysis The book is a must-read for any reliability engineer, particularly mechanical reliability professionals.

This book comprehensively outlines what a holistic and effective Root Cause Analysis (RCA) system looks like. From the designing of the support infrastructure to the measuring of effectiveness on the bottom-line, this book provides the blueprint for making it happen. While traditionally RCA is viewed as a reactive tool, the authors will show how it can be applied proactively to prevent failures from occurring in the first place. RCA is a key element of any successful Reliability Engineering initiative. Such initiatives are comprised of equipment, process and human reliability foundations. Human reliability is critical to the success of a true RCA approach. This book explores the anatomy of a failure (undesirable outcome) as well as a potential failure (high risks). Virtually all failures are triggered by errors of omission or commission by human beings. The methodologies described in this book are applicable to any industry because the focus is on the human being's ability to think through why things go wrong, not on the industry or the nature of the failure. This book correlates reliability to safety as well as human performance improvement efforts. The author has provided a healthy balance between theory and practical application, wrapping up with case studies demonstrating bottom-line results. Features Outlines in detail every aspect of an effective RCA system' Displays appreciation for the role of understanding the physics of a failure as well as the human and system's contribution Demonstrates the role of RCA in a comprehensive Asset Performance Management (APM) system Explores the correlation between Reliability Engineering and safety Integrates the concepts of Human Performance Improvement, Learning Teams, and Human Error Reduction approaches into RCA
