All clinical trials

Observational study is to increase surveillance for breast and ovarian cancers, also to determine targeted risk-reducing and preventative strategies.

is to test the hypotheses that epicardial adipose tissue can be a marker of severity of coronary artery disease in myocardial infarction patients

Peri-implant infections are severe complications after internal fracture fixation surgery. Detection of causative agents of orthopedic implant-associated infections (OIAI) is demanding. Several authors reported increased identification rates of bacterial prevalence using different sonication procedures compared to standard tissue cultures samples, especially for low grade infections. On the author hand, contamination of implants without clinical signs of infection is reported in up to 30% during implant removals after uneventful fracture healing. The raised general questions are: 1.) Is a positive microbiological finding the result of contamination during the index surgery or during implant removal? 2.) Does contaminated implants without clinical or serological signs of infection have a pathological value?

Neuraxial anaesthesia can be more difficult and associated with more complications if the patient's bony landmarks are difficult to palpate. They are more likely to be difficult to palpate if a patient has a high Body Mass Index (BMI), (>30kg/m2). The depth that the spinal or epidural needle must be inserted is usually longer in these patients with high BMIs. We wish to palpate the backs of at least 100 such patients to see how many of them have impalpable bony landmarks. We then wish to use ultrasound to measure the distance from skin to the posterior epidural complex to discover if this length is longer than the standard needle length. If it is longer in the majority of people we study, we will recommend changing standard practice to start using a longer needle for all first attempts at neuraxial anaesthesia in this patient population.

This study aims to provide the information of tissue elasticity in different etiologies of pulmonary lesions and to validate the predictive value of shear-wave elastography in differentiating benign pulmonary lesions from malignant lesions.

The aim of this study is to establish large tissue sections for 10 kinds of tumors. in order to observe the tumor landscape on microscope. The tumors including esophageal carcinoma,gastric carcinoma,hepatocellular carcinoma etc.200 cases of each tumor will be compared by traditional sample method and landscape sample method to testify the clinical value and significance of tumor landscape pathological diagnosis .

This is a prospective cohort study which aims to explore the significance of brachial and central ambulatory blood pressure monitoring in predicting cardiovascular risk in patients with end stage renal disease who are treated with hemodialysis. Enrolled patients will receive a 48-hour central and brachial ambulatory blood pressure monitoring at its first-time dialysis after enrollment. And their cardiovascular events and deaths at first and third year will be followed-up.

A prospective cohort study to assess RHEA ( recurrent vaginal bleeding, hypertension, endometrial thickness and age) scoring model for prediction of endometrial carcinoma

To quantify the diagnostic, prognostic and therapeutic value of spectrometric analysis of exhaled breath from hematological patients with respiratory infection.

Compare the Fibroscan results of preeclamptic women to normal controls and to find out if the changes are reversible after labor. Materials and Methods
