This study is to determine if suvorexant (SUV) will reduce insomnia in 76 men and women veteran and non-veterans between the ages 21-65 with posttraumatic stress disorder (PTSD) symptoms and alcohol use disorder (AUD). All participants will have a 7-day placebo run-in period, followed by a random assignment to receive placebo or suvorexant for an additonal 14 days. Post-randomization, participants will attempt to stop drinking for two weeks and will complete daily virtual diaries and study outcome assessments via in-person clinic visits on days 7 and 14.

Vitaccess Real MG (VRMG) is a patient registry designed to capture longitudinal observational data on myasthenia gravis (MG), its treatment, and impact on symptoms, daily activities, and quality of life (QoL). The duration of the registry is 10 years from launch, and approximately 600 patients will be recruited in the US and Europe with no defined upper limit. The registry will link relevant patient- and healthcare professional (HCP)-reported data with clinical data from medical records. Patients will be recruited at clinical sites in all participating countries. In the US only, patients can additionally be recruited via community neurologists or direct-to-patient recruitment.

An international randomized trial to test the primary hypothesis that perioperative tight blood pressure management reduces a composite of major perfusion-related complications (myocardial injury, stroke, non-fatal cardiac arrest, Stage 2-3 acute kidney injury, deep or organ-space infection, sepsis, and death) in the 30 days after major non-cardiac surgery. The treatments will be: 1) norepinephrine or phenylephrine infusion to maintain intraoperative MAP ≥85 mmHg (tight pressure management); or, 2) routine intraoperative blood pressure management (routine pressure management).

The purpose of the study is to test the hypothesis that functionally navigated repetitive TMS stimulations to the prefrontal cortex (PFC) modulate aberrant cortical electrical activities at PFC circuitry. The TMS location of the PFC site will be individually localized by the symptom-related functional connectivity between PFC and symptom related areas (such as the auditory and language processing cortex). The investigators predict that such modulation will correct abnormal activities in patients with schizophrenia, reduce symptoms, especially auditory hallucination, and improve working memory/sustained attention performance.

The purpose of this study is to learn about how well the 20-valent pneumococcal conjugate vaccine (20vPnC) works against radiologically-confirmed community-acquired pneumonia (RAD+CAP) due to the 7 new serotypes (types of a bacteria called Streptococcus pneumoniae that cause pneumonia) included in 20vPnC vaccine. This study is seeking participants who: - are male or female ≥65 years of age. - are hospitalized with physician suspicion of community acquired pneumonia (CAP). - have pneumonia confirmed with imaging like a chest x-ray Participants will be asked to provide demographic and medical history information, and to provide a urine sample that will be used to test for pneumonia caused by specific strains of a bacteria called Streptococcus pneumoniae. We will compare the proportion of participants who have pneumonia caused by specific strains of the bacteria Streptococcus pneumoniae and were previously vaccinated with 20vPnC with the proportion of participants who have pneumonia caused by something other than vaccine type Streptococcus pneumoniae and have been vaccinated with 20vPnC. Participants will actively take part in the study for about 1-2 days. Information on participant's illness and hospitalization details will be collected through day 30 of their hospitalization through medical chart review.

Nonalcoholic fatty liver disease (NAFLD) is a spectrum of liver conditions associated with fat accumulation that ranges from benign, non-progressive liver fat accumulation to severe liver injury, cirrhosis, and liver failure. NAFLD is the most common liver disease in US adults and the second leading cause for liver transplantation in the US. The natural history of NAFLD in the general population has been well described, with those with non-alcoholic fatty liver (NAFL, or simple steatosis) destined to have rare incidence of hepatic events compared to those with non-alcoholic steatohepatitis (NASH), who are at high risk for future development of cirrhosis, liver cancer and liver failure. The NASH Clinical Research Network (NASH CRN) was established by the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) in 2002, through the mechanism of RFA-DK-01-025, to further the understanding of diagnosis, mechanisms, progression and therapies of NASH. The NASH CRN effort has resulted in numerous seminal studies in the field. However, NASH CRN studies have systematically excluded persons living with HIV (PLWH), as NAFLD in these persons was thought to be different from that in the general population due to HIV, ART, concomitant medications, and co-infections. This has resulted in major knowledge gaps regarding NAFLD in the setting of HIV. This ancillary study of NAFLD and NASH in Adults with HIV (HIV NASH CRN), HNC 001 goal is to examine the prevalence of hepatic steatosis and NAFLD in a large, multicenter, and multiethnic cohort of PLWH (Steatosis in HIV Study)
