Obstructive sleep apnea (OSA) is a highly prevalent disorder that has major consequences for cardiovascular health, neurocognitive function, risk of traffic accidents, daytime sleepiness, and quality of life. For years, a "classic" model of OSA has been used to describe the disorder, which fails to capture it's complexity. Recently, a model for OSA called drive-dependent OSA was discovered be more prevalent in the OSA population. The drive-dependent subgroup benefits exclusively from increased ventilation, increased dilator muscle activity, and reduced event risk when drive spontaneously rises. This study seeks to provide direct evidence that reducing the loss of drive prevents the loss of ventilation, pharyngeal muscle activity, and thus the onset of OSA respiratory events, specifically in "drive-dependent" but not "classic" OSA. This will be achieved using CO2 delivered at precise times during breaths in sleep to prevent loss of overall ventilatory drive.

Small fiber neuropathy affects millions of peoples worldwide. The neuropathy is causing disabling burning pain and dysautonomia such as dizziness with standing, brain fog, fatigue, constipation, too much or too little sweating. The detection of nerve damage is complicated and not widely available; it requires either skin biopsy or specialized equipment and training. This project utilizes the mathematical processing of skin pictures for the purpose to extract the statistical features related to loss of small fibers. This approach can improve the availability of diagnosis of small fiber neuropathy.

This collaborative screening protocol, developed by the Lung Cancer Mutation Consortium (LCMC) and supported by the Thoracic Surgery Oncology Group (TSOG), is designed to determine the feasibility of comprehensive molecular profiling to detect actionable oncogenic drivers in patients with suspected early stage lung cancers scheduled to undergo biopsies to establish the diagnosis of lung cancer. The primary purpose of this testing is to determine the presence of 12 oncogenic drivers (mutations in EGFR, BRAFV600E , MET exon 14, KRAS G12C and HER2, rearrangements in ALK, RET, NTRK, EGFR exon 20 insertion and ROS1, and amplification of MET and HER2) that can serve as targets making patients eligible for upcoming targeted neoadjuvant therapy trials. The ultimate goal is to use this information from the screening process to select the optimal neoadjuvant therapy and wherever possible enroll patients onto separate neoadjuvant therapy trials with genomically matched treatments or other appropriate trials if no actionable driver mutation is detected. Thoracic Surgery Oncology Group (TSOG) is a network of surgeons within North American Thoracic Surgery Academic Centers aligned with the goal of enhancing patient care through administration of multi-site trials focused on recent advances in lung cancer. TSOG has aligned with the LCMC4 sites to enroll the LCRF-LEADER screening trial. TSOG's involvement will be essential in trial enrollment and ultimate interpretation of the multimodal clinical and translational data collected as part of this study. We estimate we will detect an actionable oncogenic driver in 33% of cases. The remaining 66% of patients will represent a cohort identified by their care teams as candidates for other potential neoadjuvant therapies which may include checkpoint inhibitors such as atezolizumab, durvalumab, nivolumab, and pembrolizumab or other novel agents. The targeted therapy treatment trials will be conducted independently of the LCRF-LEADER screening trial, evaluating for efficacy. If none of the 10 oncogenic drivers are detected, the patient will be offered participation in any clinical trial of neoadjuvant therapy available at their treating institution or standard of care therapy. For patients not enrolled on a targeted treatment trial, circulating tumor DNA in blood (ctDNA) will be collected at 3 time points: before neoadjuvant treatment, after neoadjuvant treatment but before surgery, and after surgery. This initiative will be correlated with various clinical outcomes. Prespecified clinical data will be collected for correlation with these circulating biomarkers.

Study Goal: This pilot study wants to find out if using a menstrual cup can be a good, non-invasive way to collect samples from the lining of the uterus (called the endometrium) to help screen for endometrial cancer. This is especially important for women who have a higher chance of getting this cancer, such as those with a genetic condition called Lynch syndrome. Main Questions the Study Will Answer: 1. Can a menstrual cup collect enough uterine lining (endometrial tissue) for doctors to examine under a microscope? 2. Are the samples from the menstrual cup as useful for diagnosis as samples taken using the usual method (called an endometrial biopsy or EMB)? 3. Is using a menstrual cup at home easy, effective, and comfortable for participants? 4. Can scientists grow small lab models of the uterus (called organoids) from the menstrual cup samples and from biopsy samples? What Will Happen in the Study: - Participants will use a menstrual cup at home to collect menstrual blood. - They will also have a standard endometrial biopsy done by a healthcare provider. - After both collections, participants will fill out a short survey about how comfortable and easy it was to use the menstrual cup. What the Study Will Measure: - Feasibility: How well participants are able to use the menstrual cup and send in the sample. - Sample Quality: Whether the menstrual cup collects enough good-quality tissue for testing, and how it compares to biopsy samples. - Participant Experience: How women feel about using the menstrual cup, based on the survey. - Lab Testing: Whether researchers can successfully grow endometrial organoids from both types of samples. Why This Study Matters: If this method works, it could offer a gentler, more convenient way for women to get checked for endometrial cancer-especially those who need regular screening. It could also make it easier to collect samples for research and improve early detection of cancer.

This phase III trial compares the effect of adding gemcitabine to intravesical Bacillus Calmette Guerin (BCG) versus intravesical BCG alone in patients with non-muscle invasive bladder cancer that has come back after a period of improvement (recurrent). Gemcitabine is a chemotherapy drug that blocks the cells from making deoxyribonucleic acid (DNA) and may kill cancer cells. Intravesical BCG is a solution containing the live BCG bacteria that is placed in the bladder via a catheter (intravesical). When the solution comes into direct contact with the bladder wall, it stimulates the body's immune system which kills tumor cells. Giving gemcitabine with intravesical BCG may kill more tumor cells in patients with recurrent non-muscle invasive bladder cancer.

This phase II trial evaluates whether genetic testing in prostate cancer is helpful in deciding which study treatment patients are assigned. Patient cancer tissue samples are obtained from a previous surgery or biopsy procedure and tested for deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) abnormalities or mutations in their cancer. Valemetostat tosylate is in a class of medications called EZH1/EZH2 inhibitors. It blocks proteins called EZH1 and EZH2, which may help slow or stop the spread of tumor cells. Carboplatin is in a class of medications known as platinum-containing compounds. It works in a way similar to the anticancer drug cisplatin, but may be better tolerated than cisplatin. Carboplatin works by killing, stopping or slowing the growth of tumor cells. Cabazitaxel injection is in a class of medications called microtubule inhibitors. It works by slowing or stopping the growth of tumor cells. Abiraterone acetate blocks tissues from making androgens (male hormones), such as testosterone. This may cause the death of tumor cells that need androgens to grow. It is a type of anti-androgen. Enzalutamide is in a class of medications called androgen receptor inhibitors. It works by blocking the effects of androgen (a male reproductive hormone) to stop the growth and spread of tumor cells. Lutetium Lu 177 vipivotide tetraxetan is in a class of medications called radiopharmaceuticals. It works by targeting and delivering radiation directly to tumor cells which damages and kills these cells. Assigning patients to targeted treatment based on genetic testing may help shrink or slow the cancer from growing

The study will extend recent discoveries that have been made in basic human physiology related to responses melatonin and uterine contractions in late- or full-term pregnant women. The basic physiology work has been conducted in in vitro models of the human myometrium characterizing its responses to melatonin, and in pilot in vivo studies correlating the number of uterine contractions with melatonin concentrations that were manipulated by different types of light exposure. The planned experiments will test a causal link between circulating melatonin levels and uterine contractions in full-term pregnant women by manipulating melatonin levels using exogenous melatonin (i) during the day when endogenous levels of melatonin are very low (Experiment 1), and (ii) during the evening under conditions with lighting that would be expected to suppress the higher evening and nighttime levels of endogenous melatonin (Experiment 2).

This research study is evaluating a therapy called proton beam radiation therapy (PBRT) as a possible treatment for neuroblastoma. Neuroblastoma most commonly occurs in and around the adrenal glands, which are located at the top of the kidneys. However, it can also occur in other areas where groups of nerve cells exist, such as other areas of the abdomen, neck and near the spine. Conventional radiation therapy with photons is used as standard treatment for many patients with neuroblastic tumors. In this research study, the investigators are looking at another type of radiation called proton radiation which is known to spare surrounding tissues and organs from unnecessary radiation. Proton radiation delivers radiation to the area requiring radiation. This may reduce side effects that patients would normally experience with standard radiation therapy or other means of delivering proton radiation therapy. In this research study, the investigators are evaluating the effectiveness of using proton radiation delivered to reduce side effects associated with radiation treatment. The investigators will also be assessing the late side effects experienced by participants in each treatment group.

In previous studies, Proton Beam Radiation Therapy (PBRT) has been found to show better results in treating patients with cancer, both because there is better control of where in the body the radiation is directed and because it is associated with less severe long term side effects. However, there is limited published data demonstrating these results. The goal of the Proton and Photon Consortium Registry (PPCR) is to enroll children treated with radiation in order to describe the population that currently receives radiation and better compare the short-term and long-term benefits of different types of radiotherapy. The data collected from this study will help facilitate research on radiation therapy and allow for collaborative research. The PPCR will collect demographic and clinical data that many centers that deliver radiation therapy already collect in routine operations.
