AI Screening for Diabetic Retinopathy
The increasing prevalence of diabetes mellitus represents a major health problem, especially since around 40% of diabetic patients develop diabetic retinopathy, which severely impairs vision and can lead to blindness. This development could be prevented by annual check-ups and timely referral for treatment. However, there are major differences in the …
The Role Of Circulating Tumor Cells As Markers Of Advanced Disease And Prognosis In HCC
Hepatocellular carcinoma (HCC) recurs in up to 60% of patients who undergo resection. Circulating tumor cells (CTC) have been advocated as promotors of the recurrence. However, their role as prognostic markers in the surgical setting is unclear. The aim of the present study has been to assess the association between …
Methodist Health System COVID-19 Patient Registry
This is a prospective cohort observational registry study that will include data on all patients who are treated at MHS facilities for COVID-19.
Stunning in Takotsubo Versus Acute Myocardial Infarction
The Stunning in Takotsubo versus Acute Myocardial Infarction (STAMI) Study Background: Acute myocardial stunning, herein defined as the reversible loss of myocardial function, occurs in both takotsubo syndrome (TS) and ST-elevation myocardial infarction (STEMI), and can be life-threatening in both conditions. However, despite typically having considerably more pronounced myocardial stunning, …
Combined HAIC, TKI/Anti-VEGF and ICIs as Conversion Therapy for Unresectable Hepatocellular Carcinoma
This study is conducted to evaluate the efficacy, prognosis, adverse effects, and factors for predicting therapeutic effects and clinical prognosis of combined therapy of hepatic artery infusion chemotherapy (HAIC), tyrosine kinase inhibitor/ anti-VEGF antibody, and anti-PD-1/ PD-L1 antibody for advanced hepatocellular carcinoma which initially unsuitable for the radical therapy, including …
Impact of Highly Effective Modulator Therapy on the Cystic Fibrosis Microbiome
The goal of this observational study is to learn about the effects of a specific cystic fibrosis therapy (Cystic Fibrosis Transmembrane Conductance Regulator Modulator Therapy) on chronic sinonasal disease. The main questions it aims to answer are: How does this therapy impact bacterial communities in the paranasal sinuses? How does …
Cerebral Nimodipine Concentrations Following Oral, Intra-venous and Intra-arterial Administration
Nimodipine reduces the risk of poor outcome and delayed cerebral ischemia in patients suffering aneurysmal subarachnoid haemorrhage (SAH), but its mode of action is unknown. Its beneficial effect is assumed to be due its neuroprotective effects by reducing intracellular calcium and thereby cellular apoptosis, but higher concentrations might induce marked …
High-resolution 7 Tesla MRI of C-spine - Comparison With 3 Tesla MRI
High-resolution MRI (7 Tesla) of the cervical spine is capable to differentiate osseous spurs from discus-material and better depict the compressed nerve in the neuroforamen compared to 3T MRI. Provide the surgeon with a detailed high-resolution anatomical image before surgery and potential no need for CT (if the bony anatomy …

The STOP AF First PAS is a prospective, global, multi-center, observational trial.
Water and Electrolytes Content in HYpertension (WHYSKI) in the SKIn
WHYSKI is a prospective within-patient observational clinical study designed to test the hypothesis that alterations of Na+, K+, water, and the lympho-angiogenetic transcription factor Tonicity Enhancing Binding Protein (TonEBP) mRNA take place in the interstitium of the skin compartment of patients with arterial hypertension due to primary aldosteronism in whom …
