Filter by:Constipation is a symptom based disorder with a prevalence of 15% in the adult population and its management remains challenging. Although not life threatening, constipation is associated with impaired quality of life, increased healthcare costs and excess work absenteeism. Constipation represents a heterogeneous disorder with a multifactorial pathogenesis. Several risk factors have been suggested to lead to the condition and are divided in 3 main categories: a) physiological, b) environmental and c) demographic. To date, there is lack of large epidemiological studies on proposed aetiological factors of constipation, especially studies assessing all proposed risk factors of constipation together. The overall aim of this study is to investigate the multidimensional (physiological, environmental and demographic) predictors of constipation with the use of a multivariate analysis statistical model. This is a large single centre case control study comparing constipated adults with healthy individuals matched for age, gender and ethnicity. The duration of the study is 2 weeks in total and includes a screening visit, a 2 week run-in period and a baseline visit at the end of the run-in period. Transit time between constipated and healthy individuals is assessed at baseline visit. Differences in gastrointestinal symptoms, dietary intake as well as differences in stool output (e.g. stool frequency and consistency) between constipated and healthy individuals are assessed over the baseline period (the week before the baseline visit). Differences in female sex hormone levels as well as stool markers and markers of fermentation (e.g. fecal water, stool pH, short chain fatty acids) between constipated and healthy individuals are assessed at baseline visit. Furthermore, differences in environmental measures (physical activity, anxiety, smoking) and differences in demographic measures (age, gender, body mass index) between patients suffering from constipation and healthy individuals are also assessed at baseline visit.
Acute respiratory distress syndrome following cardiac surgery severely affects the prognosis of patients; the mortality is up to 40%. Although experience many years of research and exploration, the effective methods for the treatment of acute respiratory distress syndrome is still relatively limited at present, including lung protective mechanical ventilation respiratory support, fluid management, glucocorticoid and other integrated organ function maintenance measures. It is currently the research of acute respiratory distress syndrome aims at the early discovery and takes effective measures to prevent its occurrence, hoping to improve the prognosis of patients. According to risk factors is established through the analysis of lung injury score early warning system, the early identification of acute respiratory distress syndrome patients at high risk, before the occurrence of acute respiratory distress syndrome take corresponding preventive measures can effectively reduce the incidence rate and mortality. So far, domestic and foreign research on the establishment of acute respiratory distress syndrome scoring early warning system is less. Cardiac surgery has significant characteristics, type of operation, location, operation, intraoperative blood transfusion and oxygenation, postoperative factors, are likely to be the factors of acute respiratory distress syndrome. As far as investigators know, so far there are few specialized for acute respiratory distress syndrome predicting lung injury after cardiac surgery. This study will be completed after the implementation of individualized dynamic lung injury score evaluation of cardiac surgery patients, identification of high-risk acute respiratory distress syndrome patients, to assist clinicians in early decision, take preventive measures. This study will improve the prognosis of acute respiratory distress syndrome patients after cardiac surgery; it is of great significance to improve the level of intensive care after cardiac surgery.
The purpose of this study is to establish Chinese neonatal network to investigate current situation of neonatal birth weight and related factors. We investigated the risk factors such as sex, gestational age, region, nation, altitude, place of residence, maternal occupation, education level of mother, maternal age, maternal pregnancy diseases and multiple births.
The study will assess canagliflozin (JNJ-28431754) in the treatment of patients with type 2 diabetes mellitus (T2DM) with regard to cardiovascular (CV) risk for major adverse cardiac events (MACE). Other objectives include evaluating the overall safety, tolerability, and effectiveness of canagliflozin. The data from this study will be combined with the data from CANVAS-R study (Study of the Effects of Canagliflozin on Renal Endpoints in Adult Subjects with T2DM, NCT01989754) in a pre-specified integrated analysis of CV safety outcomes to satisfy US FDA post-marketing requirements for canagliflozin.
End-stage renal disease is a global epidemia with an estimated incidence of 7% per year and high morbidity-mortality rate. Early detection of chronic kidney disease (CKD) and intervention for CKD complication is important to retard renal progression. However, "traditional uremic toxin" or "small water-soluble molecules" are poorly correlated with the renal function, uremic symptoms and outcomes of CKD patients. Putative protein-bound solute, p-cresol, is accumulated in ESRD patients receiving dialysis therapy. This uremic solute was associated with endothelial dysfunction, immune dysregulation and can predict outcome in hemodialysis patient. P-cresol inhibits endothelial cell proliferation and endothelial response to inflammatory cytokines. In vitro, p-cresol decreases leukocyte transendotherliar migratory function and inhibit production of phagocyte reactive species. Clinically, p-cresol plays a pathophysiological role in the uremic toxicity. High free serum level of p-cresol is associated with mortality in hemodialysis patients. Information of p-cresol in CKD patients is not available. The investigators hypothesized p-cresol can be accumulated in early CKD and have a positive correlation with the morbidity- mortality of CKD patients. Value of p-cresol in different stages of CRF is still unknown. Information of p-cresol in CKD patients is not available. The investigators hypothesized p-cresol can be accumulated in early CKD and have a positive correlation with the morbidity- mortality of CKD patients. The principal aim of this prospective cohort study is to investigate the association between total serum levels of p-cresol and the glomerular filtration rate. The correlation of level of p-cresol and morbidity-mortality in CKD patients will be also evaluated. To determine the relationship, patients of nephrology clinic with a diagnosis of CKD were enrolled in this prospective study and follow-up for 1-year period. The association between total and free serum levels of p-cresol and the glomerular filtration rate were evaluated in CKD patients. The p-cresol level was correlated with other many inflammatory markers (white blood cell counts, ferritin, hs-crp, leptin) and also with the hospitalization rate secondary to cardiovascular and infectious event. The renal outcome and all-cause mortality was assessed. Determination of this relationship can help to establish an accurate marker for early detection of CKD and also its prognostic role in CKD patients.
