Filter by:This is a retrospective cohort study linking data from Finnish Biobanks (Helsinki Biobank, Auria Biobank and THL Biobank), laboratory databases, and national registries of Social Insurance Institution of Finland (Kela) and the National Institute of Health and Welfare (THL) to investigate pharmacogenomics of antithrombotic drugs in the Finnish population. The purpose of the study is to assess clinical and economic aspects of using genomic data in the context of antithrombotic drug therapy. Based on earlier research, data regarding variant alleles in CYP2C9 and VKORC1 will be used in the primary analyses. Individuals with and without specific variant alleles are compared in respect to their clinical response to warfarin therapy. Warfarin-treated individuals are also analysed in relation to other clinical outcomes and a wide range of healthcare encounters. The explorative part of the study will employ data-driven classification methods to explore genotype-phenotype associations for a larger group of antithrombotic drugs including direct oral anticoagulants, clopidogrel and heparins and possible interactions with other drugs. In this part, 26 gene variants identified in literature will be used. The retrospective follow-up time for the study participants is from January 2007 to December 2018, or 2 years prior the first anticoagulant drug is purchased until 6 months after the last purchase.
Prostate cancer (PCa) is the most common solid organ cancer in North American men. Patients becoming refractory to loco-regional therapy receive androgen deprivation therapy, but their disease will inevitably progress to metastatic castration-resistant prostate cancer (mCRPC). Treatment failure and poor progression-free survival could be explained by the fact that PCa metastases in the same patient may be polyclonal, showing opposite responses to systemic therapies. This project aims to recruit 100 patients with mCRPC in order to determine the prevalence of intrapatient intermetastasis polyclonality and NED using PET/CT triple-tracer PSMA/FDG/OCTREOTATE imaging and eligibility for either PSMA or OCTREOTATE radioligand therapy (RLT).
The purpose is to examine the effects of time-restricted eating (TRE; consuming all calories within an 8-hour period each day) vs. normal eating (CON; consuming same kcals and protein as TRE, but during a 10-13 hr eating window each day) during 8 weeks of resistance exercise on body composition and muscle mass (whole muscle and single fiber), muscular performance, anabolic protein signaling, single muscle fiber characteristics, and the gut microbiome in well-trained young men and women.
The current study is a crossover trial, aiming at evaluating the effect of NAVA -NIV compared to Nasal Intermittent Positive Pressure Ventilation (PC-NIV) at the same level of peak inspiratory pressure, in terms of: breath-by-breath variability of tidal breathing amplitude, variability of the other breathing patterns; lung mechanics; gas exchange; rate of episodes of apnea; bradycardia and desaturations; respiratory asynchrony and comfort, in preterm infants < 37+0 weeks+days post-menstrual age.
Torsade de pointes (TdP) is a cardiac arrhythmia associated with QT interval prolongation which may lead to cardiac arrest. Prescription medications which cause QT interval prolongation are commonly used in daily practice. To lessen risk of TdP, pharmacists work to minimize combinations of QT interval prolonging drugs. If community pharmacists had real-time information about a patient's QT interval duration, this would have the direct ability to inform their decision making about which patients may be at highest risk of TdP and who may need heightened avoidance of QT prolonging drugs. This project will provide 3 community pharmacies with mobile ECG devices to easily determine QT intervals among patients who have a prescription profile alert for QT interval prolongation. Study outcomes will include: frequency of QT interval prolongation, changes in drug therapy related to QT interval determination, and patient and pharmacist satisfaction with having pharmacist assessment of QT interval.
The study is designed as a randomized, Double-Blind, Placebo-Controlled, Parallel-Group Proof of Concept Study (section A) with a conditional dose finding follow up (Section B) to Evaluate the Efficacy on Cervical ripening, Safety, Tolerability and dose response of Subcutaneously Administered Tafoxiparin in Term Pregnant, Nulliparous Women with an unripe cervix undergoing Labor Induction. If the efficacy and safety profiles of Section A are conclusive in favor of tafoxiparin, the study will continue by adding two additional tafoxiparin dose groups in Section B.
Helicobacter pylori (Hp) is the major cause of gastritis and gastritis-associated diseases. Detection of a regular arrangement of collecting venules (RAC) pattern in the lesser gastric curvature correlates with negative Hp status with a sensitivity and negative predictive value (NPV) higher than 90% in Asian countries. In a recent study carried out in our hospital, it has been shown that the presence of RAC pattern in the lesser gastric curvature, evaluated with high definition endoscopy, can accurately identify patients without Hp. The aim of this study is to confirm the validity of the endoscopic diagnosis of Hp infection in the West by means of the RAC pattern in a multicenter prospective study and to evaluate interobserver variability before establishing its applicability in clinical practice.
This is a randomized controlled trial (RCT) to test a novel artificial intelligence (AI)-enabled electrocardiogram (ECG)-based screening tool for improving the diagnosis and management of left ventricular systolic dysfunction.
Schizophrenia (Schizophrenia,Sc), biphasic affective disorder (Bipolar disorder,BPD), major depression (major depressive disorder,MDD), anxiety disorder (Anxiety disorder,An) and other mental disorders have obvious family aggregation, with heritability of 60 -90%. This kind of common mental illness seriously affects the psychosomatic health and quality of life of patients, and places a great mental and economic burden on the society and family. At present, the diagnosis of mental illness is mainly based on clinical symptoms. With the development of molecular biology, genomics has become a new way to study mental illness. MicroRNA (miRNA) is a class of eukaryotic endogenously non-coding single-stranded RNA, which can regulate gene expression by binding to specific mRNA or regulating the protein translation process of specific mRNA. MiRNA widely exists in plasma and serum, and the type and quantity of miRNA in plasma and serum change with different physiological and disease conditions. It is reported that the expression profile of miRNA in brain tissue of schizophrenia is significantly different from that of normal subjects. In addition, the study found that the specific miRNA detected in peripheral blood can directly reflect the condition of the disease, which may use miRNA in peripheral blood as a clinical biological marker. In order to detect the expression of various miRNA in plasma, high throughput miRNA chip detection has become the first choice for primary screening. In this study, the investigators intend to detect the difference of miRNA expression in peripheral blood of different types of schizophrenia by high throughput miRNA chip, and analyze the correlation between them. It is hoped to provide the basis for the diagnosis and occurrence and development of clinical psychotic patients.
