Filter by:The objective of this application is to illustrate the core constituents of the ocular surface microbiome, describe factors that promote colonization, and assess the ocular microbiome's role in the health of the anterior segment. We will conduct a prospective, observational cohort study, including a longitudinal analysis of the ocular microbiome in adults.
Background: Esophageal cancer commonly occurs in middle-aged man. It is ranked to the 6th common cancer and 5th cancer-related death in Taiwanese male, and sometimes co-exist with oropharyngeal cancer, which impacts our national economics and productivity a lot. To improve the prognosis of esophageal cancer, we should contribute to early diagnosis and improved treatment of the disease. Recent studies showed oral and esophageal dysbiosis may lead to oropharyngeal and esophageal cancer. Aim: To investigate whether oral microbiota is similar to esophageal microbiota. To investigate whether oral microbiota can be a non-invasive biomarker of oropharyngeal cancer, esophageal cancer, synchronous cancer and chemoradiation resistance. And whether probiotic supplement can improve oral/esophageal dysbiosis in order to prevent esophageal cancer. Study design: This study compares the oral/esophageal microbiota composition between oropharyngeal cancer cases, esophageal cancer cases, synchronous cancer cases and non-cancer controls. In addition, the link between oral and esophageal microbiota will be explored. The study will identify the microbiota related with esophageal cancer development. We will also validate the effect of probiotic supplementation on improving oral/esophageal dysbiosis. Expected result and significance: Examination of oral microbiota has the potential to become a non-invasive tool for oropharyngeal cancer, esophageal cancer, and synchronous cancer. Probiotic supplementation has the potential to improve oral dysbiosis.
Surgical site infections (SSIs) make about 31% of all nosocomial infections and they are the most common hospital-acquired infection. For foot and ankle elective interventions, SSI rate is reported between 0.4% and 3.6%. This study will investigate the effectiveness of skin cleaning with isopropyl alcohol and scrubbing with chlorhexidine soap before standard skin preparation in reducing microbial load and surgical site infections for elective foot and ankle surgeries. Current standard of care includes skin preparation with iodine or chlorhexidine solution prior to sterile draping and the start of surgery. Standard of care will be applied to all patients. The use of an additional "pre-scrub" with isopropyl alcohol and scrubbing with chlorhexidine soap will be applied to the experimental group. The control group will receive only the standard of care skin preparation with iodine or chlorhexidine solution prior to draping.
The aim of this study is to evaluate the colonization efficacy of probiotic lozenges containing dairy and dairy free probiotic Streptococcus salivarius M18, in healthy adults
The aim of this study is to evaluate the colonization efficacy of probiotic lozenges and powders containing specific prebiotics in healthy adults
To evaluate the colonisation efficacy (i.e. ability of the probiotic bacteria to remain in your mouth) of a fast melt powder that quickly dissolves in the mouth. The fast melt powder will contain a Streptococcus salivarius probiotic and the study is to be done in healthy adults.
The purpose of this investigation is to better understand the wound microbiome in burn wounds and the role it plays in outcomes and complications related to treatment.
Determining whether in the mouth there are differences between the participant groups in the nature and activity of mucosal innate immunity, in immune responses to SARS-COV2 antigens, or in the oral microbiome
Amyloidosis is a serious systemic disease. Cardiac involvement has a great impact on prognosis and can occur in its three main forms: acquired monoclonal light chain, hereditary transthyretinal and senile form. The physiopathogenesis basically results from the deposition of an abnormal protein (amyloid) with toxic properties to the myocyte. The scope of this study will be a hereditary transthyretinal amyloidosis (hATTR). It is known that amyloidotic cardiomyopathy due to transthyretin deposit is an underdiagnosed cause of heart failure in adults, being an important differential diagnosis of diseases that manifest with increased myocardial thickness, such as hypertrophic cardiomyopathy or myocardial hypertrophy that accompanies the different degrees of aortic valve stenosis. The human gut microbiota is immensely diverse. It is estimated at around 100 trillion microorganisms, including bacteria, fungi and viruses. The microbiota of each individual is unique and determined by genetic factors such as age, type of delivery, use of antibiotics and diet. Recent data point to the hypothesis that the resilience of the intestinal microbiota plays a role in the process of disease development and health restoration.
The great harm of pancreatic diseases and the unknown etiology and pathogenesis make it difficult to intervene in most early cases in time. Previous studies by scholars and applicants at home and abroad have shown that the microflora in pancreatic tissue is closely related to chronic pancreatitis and pancreatic cancer. However, the research on the mechanism of microbial diversity in pancreatic tissue and the occurrence and development of various pancreatic diseases has not been reported. Based on the previous research, this subject continues to take various pancreatic diseases as the research object based on the database of pancreatic center and pathology department of Ruijin Hospital Affiliated to Medical College of Shanghai Jiaotong University, To explore the characteristics of microbial flora in pancreas in different pancreatic diseases and its mechanism of influence on disease microenvironment. Select specific microbial flora or targets in the pancreas for various pancreatic diseases, so as to provide new theoretical basis and practical guidance for the early diagnosis and treatment of pancreatic diseases.
