Gastrointestinal (GI) diseases comprise a large spectrum of clinical conditions ranging from indigestion to inflammatory bowel diseases (IBDs) and carcinomas. Endoscopy is the usual method employed to diagnose these condition. Another noninvasive way to assess and diagnose GI conditions are fecal biomarkers. Fecal biomarkers provide information regarding a specific disease process and are perhaps more acceptable to clinicians and patients alike because of their non-invasivity compared to endoscopy. Aim of this review was to evaluate the current status of the fecal biomarkers in clinical and research for in GI diseases. Multiple types of fecal biomarkers are discussed in this review including; markers to assess IBD, which are released as a results of an inflammatory insults to intestinal epithelia such as antimicrobial peptides (lactoferrin) or inflammation related proteins (calprotectin). While markers related to function of digestion are primarily related to partially digested food or mucosal proteins such as abnormal amount of fecal fat α1-antitrypsin, elastase and secretary IgA. The upcoming fecal biomarker like M2 pyruvate kinase and neutrophil gelatinase associated lipocalin are discussed as well. Apart from above mention, the fecal biomarkers under exploration for possible clinical use in future are also discussed. These include cathelicidins, osteoprotegerin, β-glucuronidase, Eosinophil proteins, etc.
Despite having a higher mean BMI and age, women have lower RDI compared with men. Waist-to-hip ratio is more predictive of severity of OSA in men than in women. However, the correlation of anthropometric measures with severity of OSA was weak in our subjects.
Men with OSA are more likely to require higher levels of CPAP support than women. The effect of gender on CPAP requirement persisted even after correcting for the severity of OSA.
Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality. With the significant toll of the disease, more resources have been invested in developing new treatment modalities. Among these medications, inhalational anticholinergics are widely used for the management of stable COPD. The newer agents, with longer half-lives and better safety profiles, have emerged and helped to improve management of COPD patients. The available data from randomized clinical trials support use of these agents. Multiple randomized clinical trials show safety and efficacy of the newer long-acting inhaled anticholinergics, including tiotropium and aclidinium. A recent meta-analysis of tiotropium delivered with Respimat® raised some safety concerns. A large trial, comparing different doses and delivery methods of inhaled tiotropium, is ongoing to determine the effect on mortality. As clinical trials may not comprehensively represent the entire COPD population, caution should be exercised when these agents are used in higher-risk populations, like individuals with cardiac arrhythmias or urinary obstruction. In this publication, we review the safety of inhalational anticholinergics.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
