Identifying Correlates of Brain Microglial Activation in Neuropsychiatric Syndromes: A Dimensional Approach
The University of Texas Health Science Center, Houston Neuropsychiatric Syndromes
The purpose of this research is to determine whether there is more extensive inflammation in the brain of people with clinical evidence of neuropsychiatric syndromes, such as mood disorder, chronic pain syndrome, dementia, traumatic brain injury, or substance abuse. The research... expand

The purpose of this research is to determine whether there is more extensive inflammation in the brain of people with clinical evidence of neuropsychiatric syndromes, such as mood disorder, chronic pain syndrome, dementia, traumatic brain injury, or substance abuse. The research will also explore whether there is more inflammation in patients with more neuropsychiatric symptoms. Inflammation in the brain will identified by using Positron Emission Tomography (PET) with the radiotracer [11C]PBR-28.

There are two primary approaches to the treatment of OCD, pharmacotherapy and cognitive behavior therapy (CBT). Lack of therapeutic success with one approach leads to trials of the alternative approach or a combination of the two. A rarely used third therapy approach, appropriate for only the most severely afflicted and treatment resistant patients, is neurosurgical ablation of certain brain regions involved in mood and anxiety. The neurosurgical ablation procedures are irreversible in nature, and involve the destruction of specific volumes of brain tissue through various controlled means. Surgical procedures include cingulotomy, subcaudate tractotomy, limbic leucotomy which is a combination of the first two procedures and capsulotomy. DBS therapy is an alternative to neurosurgical procedures, specifically anterior capsulotomy, for patients with chronic, severe OCD which has proven resistant to primary pharmacological and/or behavior therapy options. Results from 26 severe, treatment-resistant OCD patients treated with DBS at four collaborating centers, three in the US, and one in Europe are summarized in great detail in pages 12-22 of the provided/attached "Reclaim Summary of Safety and Probable Benefit."

The purpose To determine the diagnostic potential of various biological markers in blood and cyst fluid aspirates from patients with Pancreatic Cystic Lesions (PCLs). Research design This is a 10-year prospective cohort and pancreatic cyst fluid repository study enrolling all patients diagnosed with pancreatic cyst and undergoing the cyst aspiration. Procedures to be used Blood Sample Cyst Fluid Sample Data Collection: Medical Record Number Demographics (age, sex, gender, race) Contact information History of alcohol use and IV and other recreational drugs and narcotics use/abuse Medication history Past hospitalizations, diagnoses, and treatment Physical examination findings Imaging data of abdominal and chest regions, including and not limited to ultrasonography, magnetic resonance imaging (MRI), computed tomography (CT) Future admissions, diagnoses, treatment including histopathological findings of resected specimens and blood reports End of study data: clinical progression of disease, cyst size, wall thickening, calcification, communication with pancreatic duct, string sign, cytology, immunohistochemical findings, assay levels of lipase, amylase CEA (carcinoembryonic antigen), carbohydrate antigen19-9 (CA 19-9), and other biomarkers. Risks and potential benefits The risks associated with this study are slight discomfort or bruising from the blood sampling and the possible loss of confidentiality if the patient data or information is inadvertently disclosed outside of this study. The patient will not receive any additional benefit from the study aside from those received as part of routine standard of care. Importance of knowledge that may reasonably be expected to result The knowledge gained from this study may benefit other patients with Pancreatic Cyst Lesions in the future.

Preliminary data showed that Nelfinavir has selective apoptotic effects on HPV+ cervical tumor cell lines. Furthermore, in a Phase I clinical trial, the combination of NFV and chemoradiotherapy showed acceptable toxicity and promising activity in patients with pancreatic cancer. Therefore, for the proposed research, the principal investigator will use a single-arm Phase II intervention trial study design with focus on the efficacy of NFV to induce complete or partial remission of CIN 2/3 or CIN 3 as well as biomarker evaluation.

Multi-center open-label randomized controlled trial to assess if early intervention (12.0-14.0 weeks) (study group) improves the outcome of TRAP sequence as compared to late intervention (16.0-19.0 weeks) (control group). The investigators will randomly assign women diagnosed with TRAP sequence diagnosed between 12.0 and 13.6 weeks to an early or late intervention group (1:1), using a web-based application and a computer-generated list with random permuted blocks of sizes 2 or 4 (www.sealedenvelope.com), stratified by gestational age (GA) at inclusion (11.6 -12.6 weeks versus 13.0-13.6 weeks). Analysis will be by intention to treat.
