Evaluation of a Low-Cost High Resolution Microendoscope for the Detection of Lower Gastrointestinal...
Colon PolypsColonic Dysplasia1 moreThe overall objective of this study is to obtain data to evaluate whether high-resolution imaging of the colon can assist clinicians in detecting dysplastic (precancerous) and neoplastic areas. This is a pilot study of a novel technology, a miniaturized microscope device which can be used during standard endoscopy to image the gastrointestinal epithelium. Theoretically, by visualizing superficial mucosal changes at a high-resolution and magnification, the investigators will be able to obtain optical images that can be used to guide endoscopic biopsy and polypectomy. This may foster the selective targeting of dysplasia/neoplasia, thereby improving diagnostic accuracy.
Protein Kinase A in Prostate Cancer Tissue.
Prostate NeoplasmInflammation1 moreProstate cancer is the most common malignancy in men. documented risk factors of prostate cancer are age, ethnicity, various genomic mutations and family history of prostate cancer. The cellular mechanisms of malignant transformation are numerous and not completely understood. A possible mechanism is induction of an inflammation resulting in cellular atypia and pre-malignant changes in the affected tissue by inducing a pro-inflammatory response or changes in extra cellular matrix. Protein Kinase A (PKA) is a key stone enzyme in various intra-cellular processes. Various infections' inflammations and malignancies were proved to impact PKA activity. The research hypothesis is that prostate cancer tissue will show a unique profile of PKA activity, regulation and intracellular distribution.
Predictors of Ovarian Cancer and Endometrial Cancer for Artificial-Intelligence-Based Screening...
Ovarian CancerEndometrial Cancer1 moreThe goal of this observational study is to explore the possible associated factors of ovarian cancer and endometrial cancer in Indonesia and develop screening tools that could predict the risk of both types of cancer The specific objectives of the study are Elaborating the situation of ovarian and endometrial cancer in Indonesia Exploring the possible clinical, demography and laboratory predictors of these diseases Develop artificial-intelligence-based screening tools for both type of cancer based on possible predictors This study will utilize the patient registry diagnosed with ovarian and endometrial cancer. We assumed that several demography, clinical, and laboratory predictors might possess good screening performance with higher sensitivity and specificity (>80%).
Ultrasound and Endometrial Hyperplasia
Endometrial HyperplasiaThe investigators hypothesize that endometrial thickness will be a significant predictor of endometrial hyperplasia in a postmenopausal female population with metabolic syndrome: diabetes and/or insulin resistance, hypertension, and obesity.

Spatial Proteomics Profiles of Aldosterone-producing Adenoma and Unilateral Hyperplasia
Primary Aldosteronism Due to Aldosterone Producing AdenomaPrimary Aldosteronism Due to Adrenal Hyperplasia (Bilateral)Primary aldosteronism (PA) is a common cause of secondary hypertension, which is characterized by excessive aldosterone production by the adrenal gland. Excessive aldosterone can significantly increase the risk of cardiovascular disease and stroke. Patients with aldosterone-producing adenoma (APA) or unilateral hyperplasia (UAH) can be cured by unilateral adrenalectomy. The adrenal cortex is the outer part of the adrenal gland and is subdivided into three layers- the zona glomerulosa, the zona fasciculata, and the zona reticularis. And the outermost layer is the zona glomerulosa, and it's full of cells that make the hormone aldosterone. Although it has been investigated that the main cause of APA or UAH is the mutations of different calcium ion channels, including KCNJ5, CACNA1D, CLCN2 et al, it is still unknown whether there are any other changes of other proteins in different layers. Therefore, the investigators designed the study to characterize the proteomics profiles of adrenal adenoma/hyperplasia leading to primary aldosterone and identify biomarkers for early identification of PA by using spatial proteomics. The samples from adrenal adenoma or hyperplasia will be collected and analyzed by spatial proteomics in Hangzhou Jingjie Biotechnology Co., Ltd. The differentially expressed proteins in different layers will be screened out between APA and UAH, APA and its adjacent normal tissues, and UAH and its adjacent normal tissues, respectively. And KEGG analysis will be conducted to determine enriched pathway in these differentially expressed protein, respectively.
Prospective Controlled Randomized Study of PAE vs TURP for BPH Treatment.
Benign Prostatic HyperplasiaThe purpose of this prospective randomized controlled study is to compare the improvement of symptoms from benign prostatic hyperplasia (BPH) and the improvement of QoL, in patients undergoing prostatic artery embolization (PAE) or conventional transurethral resection of the prostate (TURP).
Self-Administered Nitrous Oxide (SANO) During Transrectal Prostate Biopsy to Reduce Patient Anxiety...
Prostate DiseaseMalignancy5 moreTransrectal prostate biopsy is a commonly performed ambulatory procedure for diagnosing prostate cancer. Prostate biopsy are associated with pain or anxiety. Nitrous oxide (or laughing gas) is a well-known inhaled anesthetic which is frequently used in dental offices and for pediatric procedures to alleviate a patient's anxiety and pain. This study seeks to determine whether administration of nitrous oxide at the time of prostate biopsy will improve a patient's experience of care.
Mesenchymal Stem Cell Therapy for Bronchopulmonary Dysplasia in Preterm Babies
Bronchopulmonary DysplasiaBronchopulmonary Dysplasia (BPD) is the most frequent disease related to a premature birth, 15-50% of very low birth newborns (<1500 gr.) will develop BPD. The prevalence of BPD is increasing due to the advances in neonatology, with a rise in the survival of smaller and more premature babies. The etiology of BPD is multifactorial, in which oxygen, maternal chorioamnionitis, insufficient pulmonary maturation etc. have an important role. These factors lead to a pathological development of the lung and pulmonary vessels, developing secondary Pulmonary Hypertension (PH). Nowadays there is no efficient treatment; this generates a important sanitary burden and a decrease in life quality. Multiple experimental models in mice have studied Mesenchymal Stem Cell (MSC) therapy as prevention of BPD, also recently some clinical trials have tried this therapy on premature newborns with promising results. Hypothesis: MSC therapy in patients at high risk of BPD prevents pulmonary lesions. Methods: The investigators have designed a clinical trial to evaluate the feasibility and security of MSC therapy in patients at high risk of developing BPD.
Effectiveness of Smartconsent in Improving Understanding of Informed Consent
Benign Prostatic HyperplasiaThe general objective of the study is to assess whether the new smartconsent tool improves patients' understanding of the intervention to be performed, compared to standard practice. A randomized clinical trial will be conducted in 50 patients who will undergo LASER PROSTATIC ENUCLEATION.
